cbuildbot_config: Add debug-cidb option.

CIDB instead of Prod CIDB, and set it for assorted tryjobs that are
unsafe if run against Prod CIDB.

cbuildbot: Add --debug-cidb.

Add a new command line option to force a build to use the Debug
instance of CIDB. It's intended for advanced build infrastructure
testing that could otherwise interfere with production builds.

cbuildbot: Update CIDB selection logic.

If we are on a builder, use the Prod CIDB. If we are a local build,
don't use CIDB. Allow --debug-cidb to force Debug CIDB in any
environement.

This now true for MOST tryjobs, anything except the builds which schedule other builds.

I'm going to call this "fixed enough".
