Remove --branch-log from fast-import.

The --branch-log option and its associated code hasn't been used in
several months, as its not really very useful for debugging fast-import
or a frontend.  I don't plan on supporting it in this state long-term,
so I'm killing it now before it gets distributed to a wider audience.
