dbus nixos module: add units for systemd user session

Browse source 
This patch makes dbus launch with any user session instead of
leaving it up to the desktop environment launch script to run it.

It has been tested with KDE, which simply uses the running daemon
instead of launching its own.

This is upstream's recommended way to run dbus.
