xfs_io: allow lsattr & lsproj on foreign filesystems

xfs_io: allow lsattr & lsproj on foreign filesystems

The following commit:

commit 73b54bb6a2fb ("xfs_io: allow chattr & chproj on foreign filesystems")

allowed chattr and chproj to be run on non-xfs filesystems now that
FS_IOC_FSSETXATTR is a generic vfs call.  It failed to enable the
corresponding lsattr and lsproj commands for those filesystems, though.
