Update the recipes to move modified initrds out

Move dracut creation out of common-post so distro-specific
changes can go in without running dracut multiple times.

Pass the right kernel version into dracut so we don't pick up
whatever `uname -r` is in koji, brew, or other build
environments.

livecd-creator copies the initrd out before post script runs, so
move it out ourselves when we're done to pick up updates.
