run-tests: cleanup windows generation of the python / python3 pointeur

They are no need to generate then in RUNTESTDIR and we don't need a python2
executable. (because not test ever use `python2` explicitly).

This is probably still not perfect, but at least it is better.

Testing interaction of sparse and narrow when both are enabled on the client
side and we do a non-ellipsis clone

We only make the following assertions for the flat test case since in the
treemanifest test case debugsparse fails with "path ends in directory
separator: outside/" which seems like a bug unrelated to the regression this is
testing for.

#if flat
widening with both sparse and narrow is possible
