Revive code/hacks for building F15 images

Browse Source 
To build F15 images we need to remove systemd and set up loader as init
(see runtime-cleanup and runtime-postinstall).

We also need to add a hack to dracut so loader won't freak out when it
gets started by anaconda - see the file we're adding to the initramfs in
treebuilder.py.

(There's also an extra bonus hack for working around a bug in dracut if
/proc/cmdline is empty - SEE IF YOU CAN SPOT IT!!!)
