KLP: Install livepatches without discarding latest snapshot

The default behavior of transactional-update is to discard all changes
and copy the currently mounted snapshot. Add the missing continue flag
when installing kernel-default-livepatch so that the command doesn't
revert to the previous kernel in update_kernel.
