[CI] flaky test: not ok 19 runc run (cgroup v2 resources.unified override)

[lifubang]

Description

After #3931 merged, we don't know why the container need more memory to run, so we open an new PR #3987 to reduce the memory usage when the container staring, but I think we may need a couple of days to review and merge it.
But now, there are 2 flaky tests in CI, because the limit of memory.max, it causes the container OOM killed when starting. I think these 2 tests is not to OOM kill, but to test cgroup v2 resources.unified, so let's increase the memory limit in thses 2 tests.

Steps to reproduce the issue

1. open a PR against the main branch
2. wait CI running
3. CI failed
