Subject: [PATCH] generate e18.service using prefix, allows disabling systemd.

If one have systemd but installs to ~/ (no root) then installing
e18.service hurts.

Have e18.service to be generated using @prefix@ so it won't hardcode
to /usr/bin, removing "-locked" as that can be configured in the GUI
and in some cases you just want your e18 without lock/password.
