Upgrade py-pytest-cov from 2.9.0 to 4.0

Summary:
This is required so py-pytest-cov is functional with newer versions of
py-pytest-xdist [1].

Backport patches from upstream commit to [selectively] add 3.11 support
to make some of the tests not fail when run with newer versions of
coverage.py [2].

While here, appease portlint by shifting where variables (`CONFLICTS`,
etc) are defined.

1. pytest-dev/pytest-cov#422
2. pytest-dev/pytest-cov#570

PR:	269360
Co-Authored-With:	Yuri Victorovich <yuri@freebsd.org>

Test Plan: `make test` passes with this change.
