8ba8189ee6 TestApiStatsContainerGetMemoryLimit: Add cgroup memory test
Currently on kernels booted without the "cgroup_enable=memory" kernel
parameter the testcase TestApiStatsContainerGetMemoryLimit fails with:

FAIL: docker_api_stats_test.go:231: TestApiStatsContainerGetMemoryLimit.pN52_github_com_docker_docker_integration_cli.DockerSuite

docker_api_stats_test.go:256:
    c.Assert(fmt.Sprintf("%d", v.MemoryStats.Limit), checker.Equals, fmt.Sprintf("%d", info.MemTotal))
... obtained string = "0"
... expected string = "33759145984"

Fix this and skip the testcase if the kernel does not support cgroup memory
limit. In that case the output would be:

SKIP: docker_api_stats_test.go:231:
TestApiStatsContainerGetMemoryLimit.pN52_github_com_docker_docker_integration_cli.DockerSuite
(Test requires an environment that supports cgroup memory limit.)

ChangeLog:
----------
v4: Move TestApiStatsContainerGetMemoryLimit to docker_api_stats_unix_test.go
v3: Use existing "memoryLimitSupport" from requirements_unix.go
v2: Move check to requirements.go

Fixes #22477
