Deduplicate test names in //folly/synchronization/test:lock_test

Summary:
Give tests unique case-insensitive names

The problem here is that the tests are using prefixes like su, Su, sU and SU, but Test Infra treats test-names as case insensitive so they all end up reporting results to the same test entity: https://www.internalfb.com/intern/test/562949995823404?ref_report_id=0
