I went to add a binary file to our SVN testdata repo, and it was failing

due to checksum errors in the repo backend. I've done a dump/load to

rebuild the DB, fixing that issue.
This change also adds the new commit with a binary file which will be

used for future patching tests.
rbtools/clients/tests/testdata/svn-repo/... has been excluded from the

posted diff here, since it's just repo stuff.

Ran unit tests.
