Bug#942914: caja-mediainfo: Python2 removal in sid/bullseye

[Vlad Orlov <monsta@inbox.ru>]

Hi,

This extension seems to work with Python 3 after one import change:

-from MediaInfoDLL import *
+from MediaInfoDLL3 import *

After that, it also needs a dependency change from python-mediainfodll
to python3-mediainfodll.
