glibc: add workaround for faccessat2 being blocked by seccomp filters
Older seccomp-based filters used in container frameworks will block faccessat2
calls as it's a relatively new syscall. This isn't a big problem with
glibc <2.33 but 2.33 will call faccessat2 itself, get EPERM, and thenn be confused
about what to do as EPERM isn't an expected error code.
