This series partially supersedes:
  [PATCH v3 00/16] python/iotests: Run iotest linters during Python CI'

Howdy, this is good stuff we want even if we aren't yet in agreement
about the best way to run iotest 297 from CI.

- Update linting config to tolerate pylint 2.11.1
- Eliminate sys.path hacking in individual test files
- make mypy execution in test 297 faster

The rest of the actual "run at CI time" stuff can get handled separately
and later pending some discussion on the other series.

V2:

001/6:[0011] [FC] 'iotests: add 'qemu' package location to PYTHONPATH in testenv'
002/6:[0025] [FC] 'iotests: add warning for rogue 'qemu' packages'

- Squashed in a small optimization from Vladimir to 001, kept R-Bs.
- Fixed the package detection logic to not panic if it can't find
  'qemu' at all (kwolf)
- Updated commit messages for the first two patches.
