The Problem: Update build tools to 1.0.3

The Fix:

Updates https://github.com/drud/build-tools/releases/tag/1.0.3 - See the enhanced features mentioned there.

The Test:

There shouldn't really be any intrusive changes, but the targets for static analysis have been split out, like make govet, make gofmt. make govendor

IMO this doesn't need extensive review if it passes test and doesn't do you any harm, as the changes were reviewed upstream.

I did add two tiny commits:

• Remove the build-tools circle.yml - it certainly isn't useful here.
• Remove the include of build-tools/makefile_components/base_test_go.mak since we don't use it and it only causes a warning anyway. We're overriding it, and nothing in that include is useful.
