builtin-commit: remove .git/SQUASH_MSG upon successful commit

After doing a merge --squash, and commit afterwards, the commit message
template SQUASH_MSG in the git directory is not removed, which means that
the content of SQUASH_MSG is used as default commit message for all
subsequent commits.  So have git commit remove the file SQUASH_MSG from
the git directory upon a successful commit.

The problem was discovered by Frédéric Brière, reported through
 http://bugs.debian.org/464656
