[jdk8u-dev] RFR: 8253714: [cgroups v2] Soft memory limit incorrectly using memory.high

[Jonathan Dowland]

This is a backport of a cgroupsv2 related change for jdk8u-dev.

----

The early implementation of cgroups v2 support was done with crun 0.8 and it contained a bug which set memory.high over memory.low when --memory-reservation was being used as a CLI option.

This bug has been fixed in later crun versions, starting with crun 0.11. Use memory.low in OpenJDK as well.
