config: refactor include_by_gitdir() into include_by_path()

The include_by_gitdir() function matches the realpath of a given path against a glob pattern, but its interface is tightly coupled to the gitdir condition: it takes a struct config_options *opts and extracts opts->git_dir internally. Refactor it into a more generic include_by_path() helper that takes a const char *path parameter directly, and update the gitdir and gitdir/i callers to pass opts->git_dir explicitly. No behavior change, just preparing for the addition of a new worktree condition that will reuse the same path-matching logic with a different path.
