allow xfs_freeze to freeze "foreign" filesystems

Now that the freeze ioctl has been elevated to the VFS,
let's let xfs_io and xfs_freeze freeze other filesystems
as well - add the CMD_FOREIGN_OK flag to freeze & thaw.

I think the worst that will happen on older kernels is that
the command will fail with ENOSYS or EINVAL....
