ci: Simplify dockerfiles, add go vet steps, fix ldflag vals for alpine

- Simplify Dockerfiles a bit. Compiling a test binary can be sort of
  useful to fail quickly. But it's better to just run all the tests
  because that happens anyways. Also remove LABEL from all Dockerfiles,
  they aren't used anywhere.
- Add go vet Makefile targets. This tool is built in and provides
  valuable info.
- Make an ldflags value work better on alpine. This was more of an
  annoyance when looking at logs, than anything else. I have manually
  tested this on MacOS and Ubuntu. It works there too.
