dgit-badcommit-fixup: Honour core.sharedRepository.

Closes:#867603.

In principle it might be nicer to copy more options.  But we don't
want to duplicate the logic in prep_ud in dgit, and we don't want to
make this script too standalone.  I'm not aware of other options that
are important, rather than nice-to-have tuneables.
