tools/python: Improve unit test handling

* Add X86_{CPUID,MSR}_POLICY_FORMAT checks which were missed previously.
 * Drop test_suite().  It hasn't been necessary since the Py2.3 era.
 * Drop the __main__ logic.  This can't be used without manually adjusting the
   include path, and `make test` knows how to do the right thing.
 * For `make test`, use `-v` to see which tests have been discovered and run.
