Subject: syscallcompat: drop Faccessat AT_SYMLINK_NOFOLLOW helper
unix.Faccessat has added support for AT_SYMLINK_NOFOLLOW in July 2018,
https://github.com/golang/sys/commit/bd9dbc187b6e1dacfdd2722a87e83093c2d7bd6e#diff-341484dbbe3180cd7a31ef2ad2d679b6
which means we no longer need our own helper.
Closes https://github.com/rfjakob/gocryptfs/issues/347
