test-glog: avoid check-code violation after next patch

Danek's patch will help us avoid spurious test breakages on
Solaris. This test wasn't broken on Solaris because of the grep(1)
use, but it will upset check-code. Use cmp to silence check-code since
it doesn't matter.

import unittest, sys, os

def main(modulename):
    '''run the tests found in module, printing nothing when all tests pass'''
    module = sys.modules[modulename]
    suite = unittest.defaultTestLoader.loadTestsFromModule(module)
    results = unittest.TestResult()
    suite.run(results)
    if results.errors or results.failures:
        for tc, exc in results.errors:
            print 'ERROR:', tc
            print
            sys.stdout.write(exc)
        for tc, exc in results.failures:
            print 'FAIL:', tc
            print
            sys.stdout.write(exc)
        sys.exit(1)
