Control: affects -1 + src:dbus-python

During the binNMUs to add Python 3.9 support, dbus-python_1.2.16-3+b1
failed to build on mipsel with binutils_2.35.1-2:

   dh_dwz -a -O--buildsystem=autoconf

I don't know whether this is a binutils regression, a dwz regression or
something else. I'll try to work around it by disabling dh_dwz on mipsel
so that dbus-python isn't holding up transitions.
