Create a home directory for the 'geoclue' user
    
    Without a writable home directory, dconf (giognomeproxy uses gsettings
    to load proxy information) complains loudly, spamming system logs:
    
    dbus-daemon[708]: (geoclue:1334): dconf-CRITICAL **:
    unable to create directory '/.cache/dconf': Permission denied.  dconf will not work properly.
