BuildBot: Cleanup
Removing scripts that were placed in the source tree that would drive
the old buildbot. With the new buildbot in place these scripts aren't
being used anymore.
The buildbit is currently driven by
`build_files/config/pipeline_config.json`. In the near future make
update would also use this config.
Overview of the new buildbot: https://wiki.blender.org/wiki/Infrastructure/BuildBot
Work done by James Monteath.
