programs/gnome-session: set session systemd user units as part of NixOS

Browse Source 
While it is nice to have it as part of the desktop session package,
we're missing features which requires reimplementing parts of the
systemd-lib anyways. We can always have this later once this is
upstreamed into nixpkgs where one could modify systemd-lib to split
the unit generation step. Right now, not willing to do that.
