This thread is still lacking a conclusion about how to set up the
unitdir variables in bitbake.conf. FWIW, in my opinion this is the best
option:

export systemd_system_unitdir = "${nonarch_libdir}/systemd/system"
export systemd_user_unitdir = "${nonarch_libdir}/systemd/user"

systemd_unitdir with the old value probably needs to be kept around for
compatibility, though.
