tail,stat: improve support for the ceph file system

Teach tail -f that it must use polling on ceph file systems, and
let stat -f --format=%T report the file system type name, "ceph".
Website: http://ceph.com/

* src/stat.c (human_fstype): Add a case: ceph, 0x00C36400, remote.
* NEWS (Improvements): Mention it.
* THANKS.in: Update.
