contrib: dracut: zfs-{rollback,snapshot}-bootfs: explicit snapname fix
Due to a missing semicolon on the ExecStart line, it wasn't possible
to specify the snapshot name on the bootfs.{rollback,snapshot}
kernel parameters if the boot dataset name was obtained from the
root=zfs:... kernel parameter.

Add bootfs.snapshot and bootfs.rollback kernel parameters
Unlike other filesystems, snapshots and rollbacks of bootfs need to be
done from a rescue environment. This patch makes it possible to snap-
shot or rollback the bootfs simply by specifying bootfs.snapshot or
bootfs.rollback on the kernel command line. The operation will be
performed by dracut just before bootfs is mounted.
