Fix CI build and coverage gathering

* Default Mac image has been changed on Travis. Use `pip2` instead of `pip`.
* Don't install bit32 on Appveyor or luacov-coveralls on Travis.
  luacov-coveralls isn't used anymore.
* Pass luacov.report.out to codecov explicitly on Appveyor, it doesn't
  find it there. Also disable gcov run.
* Use cluacov, should hopefully improve speed and coverage accuracy.
* Use the new location for coverage files (testrun instead of test).
