redhat: add more namespace selftests to kernel-modules-internal package

Upstream Status: RHEL-only
JIRA: https://issues.redhat.com/browse/RHEL-95481

As the time of this commit there is no targeted testing in CKI for the
namespace subsystem. Two other kselftests are in the process of being
enabled: pid_namespace and rlimits. Adding two more, timens and pidfd
will allow us to increase targetting CKI testing even further.
