xfstests: move xfs specific tests out of top directory

And into tests/xfs. Tests found and moved via:

$ grep "supported_fs xfs$" [0-2]* | cut -d : -f 1 > xfs.tests
$ for i in `cat xfs.tests`; do
> git mv $i* tests/xfs/
> grep ^$i group >> tests/xfs/group
> sed -i -e "/^$i/d" group
> done

Output now looks like:

 sudo ./check -g quick -r
FSTYP         -- xfs (debug)
PLATFORM      -- Linux/x86_64 test-1 3.5.0-rc5-dgc+
MKFS_OPTIONS  -- -f -bsize=4096 /dev/vdb
MOUNT_OPTIONS -- /dev/vdb /mnt/scratch
