Don't use -1 fd and AT_SYMLINK_NOFOLLOW for faccessat()
-1 is not an allowed value for the file descriptor, the only
allowed non-file-descriptor value is AT_FDCWD. So use that
instead.
AT_SYMLINK_NOFOLLOW has a weird semantic: It checks whether
we have the specified access on the symbolic link. It also
is implemented only by glibc on Linux, so it's inherently
non-portable. We should just drop it.
Thanks: James Clarke for debugging these issues
