xorg-server: enable privilege-less Xorg

Description:
#### Testing the changes
- I tested the changes in this PR: **briefly**  
  I haven't daily driven these changes, but the affected areas I've tested, and I believe anyone who has the right groups should be alright.

There's actually no dependency on any library but DBus when enabling elogind, so I removed that false dependency. Changing `Xwrapper.config` to have `auto` by default should  prevent breaking anyone's system.
