Filter out .exe interpreters on WSL

On WSL pythonfinder will find interpreters on Windows and may pick from them, while not working at all.

seems good to me, what shows up as os_name on WSL?

Just the same as a normal *nix system: posix

I need to check later, but IIRC Linux (ELF) Python installations report posix, but Windows Python installations (python.exe) report nt.

Edit: yup

$ /home/uranusjr/.local/share/pythonup/cmd/python3.6 -c 'import os; print(os.name)'
posix
$ /mnt/c/Users/uranusjr/AppData/Local/Programs/Python/Python36/python.exe -c 'import os; print(os.name)'
nt

So the implication here is that it's definitely appropriate to exclude things with an exe extension when running inside WSL
