Package build provides details of the built binary
The details are set using ldflags.
The ldflags can be set manually for testing locally:
`go build -ldflags "-X github.com/gomods/athens/pkg/build.version=$(git describe --tags) -X github.com/gomods/athens/pkg/build.buildDate=$(date -u +%Y-%m-%d-%H:%M:%S-%Z)"`
