8254854: [cgroups v1] Metric limits not properly detected on some join controller combinations

[kvergizova]

I'd like to backport 8254854 to 13u for parity with 11u.
The patch doesn't apply cleanly since 13u doesn't have cgroups v2 support (JDK-8231111), so it reapplied manually to Metrics::setSubSystemPath() method instead of CgroupV1Subsystem::setSubSystemControllerPath() from the original patch.
Tested with tier1 and container tests.
