Roll back --user and --group functionality

I'd much rather let systemd handle this -- it's going to be done more
cleanly and without potential badness caused by loading the entire python
environment as root.

See the comments in systemd example files in contrib/ on how you can
override the default "mirror" user/group via systemd drop-in conf
files.
