[PATCH 3/3 v2] xfstests: allow 091 for non-xfs filesystems

[Christoph Hellwig <hch@xxxxxxxxxxxxx>]

The tests in 091 are entirely generic and pass e.g. on ext4 and jfs.
btrfs fails it, but that looks a like a btrfs-specific issue to me.

Also use _supported_os properly instead of erroring out manually on
IRIX.
