build: Make post-install script a Python script

The existing post-install shell script will most likely not work on
Visual Studio builds as there is normally no shell interpreter installed
on the system where the build is done, but the build is normally done in
a standard Windows cmd.exe console.

Instead, use a Python script so that it will work on the platforms that
Python supports.
