Merge #720: CI: Use specific revision of maintainer-tools

dc7ed26 CI: Use specific revision of maintainer-tools (Tobin C. Harding)

Pull request description:

  We don't want to pull the maintainer tools repo from master otherwise we cannot patch it, we should use a specific revision.

  This was an oversite in the original work when introducing the maintainer tools `run_task` script.

  Use commit:

    ACK dc7ed26
  apoelstra:
    ACK dc7ed26 successfully ran local tests; though once it stabilizes a bit we may want to start adding tags to maintainer-tools (maybe with just the date) to make it more visually obvious when we get out of date
