tests: fix PYTHONPATH manipulation on Windows

Without the semicolon separator and quotes, the variables ends up like this:

    c:\Users\Matt\projects\hg-evolve:c:\Users\Matt\projects\hg-evolve:
    c:\Users\Matt\projects\hg;c:\Users\Matt\projects\hg-evolve\tests;
    c:\Users\Matt\projects\hg\tests

That in turn makes the local evolve code unreachable, and the system installed
code is tested instead.

I'm testing against `uname` instead of a trivial python script printing os.name
because maybe one day tests will run on WSL.
