Makefile: Simplify (#62)

This simplifies the Makefile significantly,
borrowing patterns we've used in other projects.
Namely:

- Set GOBIN to a bin subdirectory
  so that we can `go install` dependencies into it.
- Use a shared TEST_FLAGS for `make test` and `make cover`.
  Without this, we're not running with data race detection in CI.
- Build lint step out of separate golint and staticcheck steps.
  In the future, a gofmt step may also be added.
- Move tools dependencies into an unpublished subpackage.

Note: I didn't mess with the 'clean' and 'run' targets
at the bottom of the file even though they're not necessary
to avoid a merge conflict with #60.
