unix: check Faccessat2 returning EPERM in Faccessat

Some systems (e.g. the linux-arm and linux-arm64-packet builders) return
EPERM instead of ENOSYS on unimplemented syscalls. Fall back to the
existing glibc-like implementation in Faccessat in this case as well.

This fixes tests on the linux-arm and linux-arm64-packet builders after
CL 246537.
