getopt: fix build on clang 16
Normally, when getopt builds on a non-glibc platform, it uses C library headers without including them. That’s fine unless your compiler is clang 16, which is strict about using functions without prototypes. Fortunately, Darwin’s headers are compatible enough as are Musl’s, so defining `__GNU_LIBRARY__` can be done unconditionally.
