  python: Fix tests on MinGW
  
  Add the directory containing libxml2.dll with os.add_dll_directory to
  make tests work on MinGW.
  
  This has changed in Python 3.8 but for some reason, the issue only
  turned up with Python 3.11 on MinGW. Contrary to documentation, copying
  libxml2.dll into the directory containing the .pyd file doesn't work.
