Skip kernel-memory tests on RHEL/CentOS daemons
RHEL/CentOS 3.10 kernels report that kernel-memory accounting is supported,
but it actually does not work.

Runc (when compiled for those kernels) will be compiled without kernel-memory
support, so even though the daemon may be reporting that it's supported,
it actually is not.

This cause tests to fail when testing against a daemon that's using a runc
version without kmem support.

For now, skip these tests based on the kernel version reported by the daemon.

This should fix failures such as:

```
