Subject: Fix compilation under clang

Makes uses of _FORTIFY_INLINE and _FORTIFY_POS0 in sys/select.h,
as clang complains about __gnu_inline__ in some cases. An issue
which is already fixed with the shared macros.

It was reported it:
- https://gitlab.alpinelinux.org/alpine/aports/-/issues/18015
- https://gitlab.alpinelinux.org/alpine/aports/-/issues/18000
