uuid could try fallback methods that had no chance of working on a particular platform, and this could cause spurious test failures, as well as degraded performance as fallback options were tried and failed. This fixes both the uuid module and its test's SkipUnless logic to use a prefiltered list of techniques that may at least potentially work on that platform. Patch by Michael Felt (aixtools).
