debian/lib/python/debian_linux/gencontrol.py: Delete broken methods

MakeFlags.__repr__ references a "flags" type (probably meant to be
MakeFlags).  Gencontrol.write_config references the "file" type which
was removed in Python 3.  Clearly neither of these methods are
actually used, so delete them.
