dash: Bind libedit's secret filename completion function
Check if the FreeBSD (and by extension macOS) _el_fn_sh_complete version
of the function exists, which does shell escaping of completed filenames
before _el_fn_complete learned to.

Tab is bound after calling el_set() and el_source() since the default
bindings set tab to something else, and it should always be filename
completion in the shell.
