remove old CI badges and configs

I'm not looking at Coveralls anymore, and getting it working with GitHub
Actions on other projects has been a pain, so I'm removing that too. Not
opposed to adding code coverage back to CI in the future, though, if
anyone else is enthusiastic about some particular tool.
