[kvm-unit-tests GIT PULL 13/13] s390x: skey: Fence TCG protection checks

[Janosch Frank <frankja@linux.ibm.com>]

TCG does not implement the skey memory protection, skip those tests
under TCG instead of filtering them in the CI logs.

This way the test will PASS when run by humans and there's no
confusion why it fails anymore.
