difftool: use Git::* functions instead of passing around state
Call Git::command() and friends directly wherever possible. This makes it clear that these operations can be invoked directly without needing to manage the current directory and related GIT_* environment variables. Eliminate find_repository() since we can now use wc_path() and not worry about side-effects involving environment variables.
