tests: containers: Skip if setgroups file does not exist.
Fixes bug #21226. Linux 3.19 introduced a fix for a security vulnerability in user namespaces. This fix introduced a new proc file called 'setgroups' and was backported to many older kernels. However, some users run a kernel that is new enough to support user namespaces yet old enough to not include the patch, so we must skip the tests. * tests/containers.scm: Skip all tests if /proc/self/setgroups does not exist.
