Add test suite to validate the s390x architecture specific ucontrol KVM interface.

Make use of the selftest test harness.

• uc_cap_hpage testcase verifies that a ucontrol VM cannot be run with hugepages.

To allow testing of the ucontrol interface the kernel needs a non-default config containing CONFIG_KVM_S390_UCONTROL. This config needs to be set to built-in (y) as this cannot be built as module.
