Render option to git commit configurable

When etckeeper commit something it use a default message that can be
configured, but not easily edited on a case by case basis.

To make this possible, and to give other way to customize commit, I
add a configuration file that contain for now only one option:
GIT_COMMIT_OPTION that can contain option given to git commit when run
by etckeeper
