[Buildroot] [git commit branch/2020.02.x] package/python3: do not install MS Windows installers on the target

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=5a31e4f56544fb35179039ac6f7d35ee914ebcba
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x

Buildroot generates Linux systems, so there is no need to have
MS Windows executables in there.

This reduces the target filesystem size by about 2MB:
