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. 2020-12-03 01:41:38 +03:00			`# A VERY small memory.high will cause the script (trying to use a lot of memory)`
