Rename build script to avoid conflict with bazel

It's difficult to include this repository using bazel, because
the file named "build" conflicts with new_go_repository generation
on case-insensitive filesystems (ref
https://github.com/bazelbuild/rules_go/issues/234). This change
renames the file to something that doesn't conflict, and also
renames the test script for consistency.

 - If you changed code:
    - add automated tests to cover your changes, using the [Ginkgo](http://onsi.github.io/ginkgo/) & [Gomega](http://onsi.github.io/gomega/) style
    - if the package did not previously have any test coverage, add it to the list
