Add test case running code interacting with registers within a
ucontrol VM.
* Add uc_gprs test case
The test uses the same VM setup using the fixture and debug macros
introduced in earlier patches in this series.

Add a uc_kvm fixture to create and destroy a ucontrol VM.
* uc_sie_assertions asserts basic settings in the SIE as setup by the
kernel.
* uc_attr_mem_limit asserts the memory limit is max value and cannot be
set (not supported).
* uc_no_dirty_log asserts dirty log is not supported.

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.
