KVM: selftests: Test all possible "invalid" PERF_CAPABILITIES.LBR_FMT vals
Test all possible input values to verify that KVM rejects all values except the exact host value. Due to the LBR format affecting the core functionality of LBRs, KVM can't emulate "other" formats, so even though there are a variety of legal values, KVM should reject anything but an exact host match.
