  CI: Add Flake8 check for selected tests (#2199)

grass.jupyter and grass.script tests are almost Flake8 compliant. This fixes the reported issues and removes Python 2 specific check.

A new step in the flake8 job checks explicitly for the files in the two testsuite directories. (There is no way in Flake8 itself to include previosly excluded files which is needed because testsuite directories are ignored in the main .flake8 file and here we need to check them.)
