build: commit generated code files (#449)

* build: commit generated code files

Keeping these files in the repository will help with vendoring
and should make the package "go get"-able.

* build: ignore generated files in code coverage

* build: add "make validate-generated" target

This should ensure go-bindata files are kept up to date.

* fix: replace script with simpler git commands

* fix: revise git diff command for generated file check
