Improve speed and clarity of code coverage

Rationale:
- tox should work the same as before
- coverage is too slow and disabled by default locally
- disable coverage on pypy and pypy3 (way too slow)
- add coverage info for pkg_resources
- make sure tests are ignored in coverage
- make sure all CI jobs are identifiable
- include coverage for xfail (too complicated otherwise)
- disable report on terminal
