Lennart Poettering 2ec71e439f journald: slightly bump OOM adjust for journald (#13366)
If logging disappears issues are hard to debug, hence let's give
journald a slight edge over other services when the OOM killer hits.

Here are the special adjustments we now make:

 systemd-coredump@.service.in OOMScoreAdjust=500
 systemd-journald.service.in  OOMScoreAdjust=-250
 systemd-udevd.service.in     OOMScoreAdjust=-1000

(i.e. the coredump processing is made more likely to be killed on OOM,
and udevd and journald are less likely to be killed)
