This should be set in environment of srarted systemd, which in case of
systemwide init effectively means either you need to use some wrapper to
set it and exec systemd or hack initrd.

Also SYSTEMD_UNIT_PATH does not really play nicely with priorities of
unit locations (run-time vs. sysadmin vs. shipped).

May be it is simpler to install generator that copies your unit
definition in standard location. This guarantees it is available before
systemd starts.
