[PATCH] Remove unused sh functions from git-mergetool.sh

The tidy up of git mergetool's backup files handling made the two shell
functions save_backup and remove_backup redundant. This commit removes
these now unused functions.

This patch belongs on top of the mergetool updates in pu. It removes a
couple of shell functions which were made redundant in commit
6fef6e2...  In fact it should logically be squashed into that commit.
