Account for interface files for swap and memory being reported independently.
The cgroup v1-like value is now reported by adding the memory.max value to
the memory.swap.max value, and memory.current and memory.swap.current
respectively.

ff6843ca48 8253714: [cgroups v2] Soft memory limit incorrectly using memory.high 
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.
