package/libselinux: fix build with musl
musl does not define glibcisms, so we are missing some macros.
Define what we need in case the macro is missing. We're using a dumb
implementation, which is rather slow, to avoid copying from glibc, to
avoid propagating the LGPL to libselinux, which is Public Domain.
Fixes a bunch of autobuild failures:
