A better check out be:

if [ {D}${prefix}/lib/systemd != `dirname ${D}${systemd_unitdir}` ]; then
   install -d `dirname ${D}${systemd_unitdir}`
   mv ${D}${prefix}/lib/systemd `dirname ${D}${systemd_unitdir}`
   rmdir ${D}${prefix}/lib --ignore-fail-on-non-empty
fi

This way the issue is resolved even if usrmerge isn't enabled, but the user
manually manipulated the paths.
