[issue16620] Avoid using private function glob.glob1() in msi module and tools

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

It looks to me that the glob() method of msilib.Directory is broken from the born. It uses the function from the glob module, but the glob module is not imported in this source file.

Even if add missed import, returned value is incorrect in Python 3. In Python 2 glob.glob1() always returned a list, but in in Python 3 it can return an empty list or an iterator. After iterating on it msilib.Directory returns an empty list or exhausted iterator.

type: enhancement -> behavior
