tmpfs: fix XATTR N overriding POSIX_ACL Y
Choosing TMPFS_XATTR default N was switching off TMPFS_POSIX_ACL, even if it had been Y in oldconfig; and Linus reports that PulseAudio goes subtly wrong unless it can use ACLs on /dev/shm. Make TMPFS_POSIX_ACL select TMPFS_XATTR (and depend upon TMPFS), and move the TMPFS_POSIX_ACL entry before the TMPFS_XATTR entry, to avoid asking unnecessary questions then ignoring their answers.
