[BUILTIN] Disable ulimit if there is no getrlimit

For systems without getrlimit (e.g., klibc) we will disable ulimit.

In order to achieve this, builtins.def is now produced by cpp which
allows us to use macros such as HAVE_GETRLIMIT in it.

Thie also means that we can get rid of the cflags parsing code in
mkbuiltins.
