PATCH 1/1 kernel-configs: enable namespace support

At this time there is only one xfstest that requires namespaces support (overlay/020) and it requires user namespace support. This test fails with default kvm-xfstests configs.

Recently, a regression with overlayfs was reported relating to mount ns, so tests that require only mount ns may be needed too.

This change re-enables the kernel default namespace support for all kernel configurations and enables user ns support for stable kernels v3.18 and above, where user ns is considered stable and maintained.
