This adds a build script and a settings file for "mkosi", a tool for putting
together full, bootable disk images for container managers of EFI systems and
VMs.
With these files it's enough to type "mkosi" in the project directory to
generate a bootable Fedora 24 OS image with a version of systemd compiled fresh
from the working tree.
