KVM: selftests: Print a message if /dev/kvm is missing
If a KVM selftest is run on a machine without /dev/kvm, it will exit silently. Make it easy to tell what's happening by printing an error message. Opportunistically consolidate all codepaths that open /dev/kvm into a single function so they all print the same message. This slightly changes the semantics of vm_is_unrestricted_guest() by changing a TEST_ASSERT() to exit(KSFT_SKIP). However vm_is_unrestricted_guest() is only called in one place (x86_64/mmio_warning_test.c) and that is to determine if the test should be skipped or not.
