Add coreos-installer-systemd subpackage

Systemd units and supporting executables were added upstream in
https://github.com/coreos/coreos-installer/pull/119. Let's add a
subpackage so we can deliver them in Fedora, but separate from the
main installer binary that people may want to execute outside of the
service.
