Bump to 247.3-2 for systemd-oomd finishes and systemd-oomd-defaults subpackage

Browse Source 
Changes for https://fedoraproject.org/wiki/Changes/EnableSystemdOomd.
Backports primarily PR #18361, #18444, and #18401 (#18401 is not merged
at the time of writing this commit) + some minor PRs to handle conflicts.
Creates systemd-oomd-defaults subpackage to install unit drop-ins that
will configure systemd-oomd to monitor and act.

Subject: [PATCH] test: fix TEST-56-OOMD thresholds for linux 5.9 changes
Fixes #17533
The memory pressure values of the units in TEST-56-OOMD seemed to be a
lot lower after updating to linux 5.9. This is likely due to a fix from
https://github.com/torvalds/linux/commit/e22c6ed90aa91abc08f107344428ebb8c2629e98.
To account for this, I lowered memory.high on testbloat.service to
throttle it even more. This was enough to generate the 50%+ value to trigger
oomd for the test, but as an extra precaution I also lowered the oomd
threshold to 1% so it's certain to try and kill testbloat.service.

Subject: [PATCH 3/4] oom: fix reclaim activity detection
This should have been checking for any reclaim activity within a larger interval
of time rather than within the past second. On systems with swap this
doesn't seem to have mattered too much as reclaim would always increase when
memory pressure was elevated. But testing in the no swap case having
this larger interval made a difference between oomd killing or not.

Subject: [PATCH 2/2] oom: rework *MemoryPressureLimit= properties to have
1/10000 precision
Requested in
https://github.com/systemd/systemd/pull/15206#discussion_r505506657,
preserve the full granularity for memory pressure limits (permyriad)
instead of capping out at percent.
