xfs: add debian initramfs hook to package

In Debian bug 904086, the reporter complained that xfs_repair wasn't
present in the initramfs, which prevented him from using shutdown -F to
force a filesystem fsck after a reboot.  Add a hook to put the xfs
utilities in the initramfs if xfs is the root filesystem.
