8275735: [linux] Remove deprecated Metrics api (kernel memory limit)

[jerboaa]

Please review this change to remove some API which no longer works as expected as recent OCI runtimes start to drop support for --kernel-memory switch. See the bug for references. This part of the API is not present in hotspot code.

Testing: Container tests (cgroup v1) on Linux x86_64 (all pass)
