unix: check faccessat flags parameter on Linux

Browse Source 
Currently Linux faccessat(2) syscall implementation doesn't support the
flags parameter. As per discuss in golang/go#25845, permit the same flags
as glibc [1].

[1] https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/faccessat.c;h=ea42b2303ff4b2d2d6548ea04376fb265f773436;hb=HEAD

Fixes golang/go#25845
