strbuf: add strbuf_add_real_path()
Add a function for appending the canonized absolute pathname of a given path to a strbuf. It keeps the existing contents intact, as expected of a function of the strbuf_add() family, while avoiding copying the result if the given strbuf is empty. It's more consistent with the rest of the strbuf API than strbuf_realpath(), which it's wrapping. Also add a semantic patch demonstrating its intended usage and apply it to the current tree. Using strbuf_add_real_path() instead of calling strbuf_addstr() and real_path() avoids an extra copy to a static buffer.
