filter-branch.sh: remove temporary directory on failure

Browse Source 
One of the first things filter-branch does is to create a temporary
directory. This directory is eventually removed by the script during
normal operation, but is not removed if the script encounters an error.

Set a trap to remove it when the script terminates for any reason.
