With QtWebKit it's probably okay to still use it (*cough* Hyperbola
GNU/Linux-libre^tm *cough*), and only blacklisting it with QtWebEngine would be

Fixes#3608
This eliminates all separate pytest envs in favor of conditionals in
[testenv]. This requires renaming some environments to make the lack of
certain functionality explicit:
- instead of omitting pyqt{version}, use pyqtlink to use host PyQt
tox.ini: eliminate -nocov
It is possible to set the `PYTEST_ADDOPTS` environment variable to
enable coverage checks, rather than a new command.
