inconsistent buggy and fixed revision information for gzip-2009-09-26-a1d3d4019d-f17cbd13a1

[manishmotwani3]

In the gzip scenario the file bug-info/scenario-data.txt shows the commit hashes of the buggy and fixed versions as follows:
bug revision: 3eb6091d69a
fix revision: 884ef6d16c6
however, none of these commit hashes exists in the filenames of the buggy and fixed version of the files and nor in the scenario name.

scenario-data.txt comes straight from the original ManyBugs archive. The rest of the files in the archive otherwise look consistent with the name of the scenario.

It may be that the whole of scenario-data.txt needs to be updated. If that's the case, then it would probably be better if the original archive was updated, rather than applying a special-case patch to the Docker container image.
