Remove wcwidth port

DYLD_FORCE_FLAT_NAMESPACE no longer exists in macOS 12 so this
approach doesn't work anymore. Moved to
<https://git.causal.agency/jorts/tree/wcwidth> and compiled into
<https://git.causal.agency/jorts/tree/ncurses>.

-The TRE regular expression implementation (src/regex/reg* and

-under a 2-clause BSD license (license text in the source files). The
-included version has been heavily modified by Rich Felker in 2012, in
-the interests of size, simplicity, and namespace cleanliness.

-and labelled as such in comments in the individual source files. All
-have been licensed under extremely permissive terms.
-
-The ARM memcpy code (src/string/arm/memcpy_el.S) is Copyright © 2008
-The Android Open Source Project and is licensed under a two-clause BSD
-license. It was taken from Bionic libc, used on Android.
-
-The implementation of DES for crypt (src/crypt/crypt_des.c) is
-Copyright © 1994 David Burren. It is licensed under a BSD license.
-
-The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was
-originally written by Solar Designer and placed into the public
-domain. The code also comes with a fallback permissive license for use
-in jurisdictions that may not recognize the public domain.
-
-The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
-Valentin Ochs and is licensed under an MIT-style license.
-
-The x86_64 port was written by Nicholas J. Kain and is licensed under
-the standard MIT terms.
-
-The mips and microblaze ports were originally written by Richard
-Pennington for use in the ellcc project. The original code was adapted
-by Rich Felker for build system and code conventions during upstream
-integration. It is licensed under the standard MIT terms.
-
-The mips64 port was contributed by Imagination Technologies and is
-licensed under the standard MIT terms.
-
-The powerpc port was also originally written by Richard Pennington,
-and later supplemented and integrated by John Spencer. It is licensed
-under the standard MIT terms.
-
-All other files which have no copyright comments are original works
-produced specifically for use as part of this library, written either
-by Rich Felker, the main author of the library, or by one or more
-contibutors listed above. Details on authorship of individual files
-can be found in the git version control history of the project. The
-omission of copyright and license comments in each file is in the
-interest of source tree size.
-
-In addition, permission is hereby granted for all public header files
-(include/* and arch/*/bits/*) and crt files intended to be linked into
-applications (crt/*, ldso/dlstart.c, and arch/*/crt_arch.h) to omit
-the copyright notice and permission notice otherwise required by the
-license, and to use these files without any requirement of
-attribution. These files include substantial contributions from:
-
-Bobby Bingham
-John Spencer
-Nicholas J. Kain
-Rich Felker
-Richard Pennington
-Stefan Kristiansson
-Szabolcs Nagy
-
-all of whom have explicitly granted such permission.
-
-This file previously contained text expressing a belief that most of
-the files covered by the above exception were sufficiently trivial not
-to be subject to copyright, resulting in confusion over whether it
-negated the permissions granted in the license. In the spirit of
-permissive licensing, and of not having licensing issues being an
-obstacle to adoption, that text has been removed.
