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.
It causes stuff to blow up when something in there got upgraded, and we ask pip
to downgrade one of its dependencies.
We still keep the file around so we get notified about updates.
