Add script to support PyInstaller under Wine

On a vanilla invocation, `wine-pyinstaller.sh` will prepare a
Python-3.5 environment under Wine-3. The current requirements to run
the script are following:

  1. p7zip-16.xx
  2. Wine-3.xx
  3. WinPython-3.5.4

All of [1-3] are available in Debian Testing or Ubuntu Bionic
repositories.

P.S.

WinPython was used since official Python-3.5.4 from Python.org wont
run under Wine. Python-3.6 is not supported yet under Wine-3.xx.
