To significantly reduce the PMU counter test's runtime, without sacrificing test coverage in the aggregate, test a random GP counter in the arch events testcase instead of testing every possible GP counter. Testing every PMC in every run of the test significantly increases the runtime of the test, without providing an equivalent increase in validation coverage, as the odds of a KVM having a bug that only affected a subset of counters and only when testing all other counters are extremely low. Opportunistically clean up kvm_random_u64_in_range() to eliminate unnecessary newlines.
