Convert most of 52-update-rc.d to a systemd.preset(5) file

This would be more declarative, instead of running commands at ISO build time.

• http://freedesktop.org/wiki/Software/systemd/Preset
• dlocate ‘\.preset$’ for the file format
• run systemctl preset-all in a chroot local hook

(Not a blocker for 2.0, but would be a nice cleanup :)
