Previous versions of the package give _osrm_routed a nonexistent home
directory, causing errors when using the rc script in certain situations.
This can't be fixed by updating the package alone.
N.B.: if you've EVER installed osrm-backend, wait for the package
mirrors to update with osrm-backend5.18.0p1, and then run the following:
# pkg_delete osrm-backend
# userdel _osrm_routed
After doing so, you can safely re-add the package.
