Get rid of more lintian complaints from github Python linter.

While working on https://github.com/FreeCAD/FreeCAD/pull/9867 I noticed my patch
showed up with a lot of linting issues in code I did not touch, to a point
where the view was very cluttered by lintian issues.  Here is my second
try to reduce the number of issues discovered by the linter.  Some
issues are still left, as I fail to see how to sensibly reduce the number of
parameters or local variable used.
