Reduce oom score adj of Dbus Broker
Dbus broker uses 1.2GB and dosent get earlyoom killed until every other process is killed
due to its oom_score_adj value of -900. Reducing it to -600 to allow other processes
to stay alive when dbus broker uses >90% of the system's memory.
I see a 60 oom score decrease for every 100 adjust. Currently using 95% of the system's
memory has a badness score of 662. Now it should have a score of 842, which should be killed
early on in the earlyoom kill streak.
I see around 670 as the average badness score of other processes on the system.
Tested:
Messed around w oom score adj on real machine.
