testbot: Let VM scripts identify the last part of a patchset.
For patchsets (and subsets thereof) the Engine calls GetPatchImpacts() at least once with only the last part. This allows it to know exactly what the last part modifies and thus what needs to be retested. However the VM scripts only have the full patchset so they don't know what the last part is. Thus they are forced to rerun every test touched by the full patchset. So the TestBot now adds a marker before the last part, allowing GetPatchImpacts() to identify it. Note that it does not use '---' as that marker may or may not be present depending on how the patch was formatted for emailing (and can be ambiguous too).
