[libvirt] [PATCH v4 03/26] build-aux: rewrite po file minimizer in Python
As part of an goal to eliminate Perl from libvirt build tools,
rewrite the minimize-po.pl tool in Python.
This was a straight conversion, manually going line-by-line to
change the syntax from Perl to Python. Thus the overall structure
of the file and approach is the same.
