gitconfig: Add sample checks shipped by git to pre-commit hook

Several checks are listed in git’s example hook files. So use the
    ones from the pre-commit hook. They check for non-ascii file names
    and whitespace errors.

The `exec` calls are removed and `set -e` is added to abort the
    commit, when one of the tests fails.

Please run `make gitconfig` to get the updated hooks.
