Subject: [PATCH] tools/backport_pr.py: improve usability

Add `search_parent_directories=True` to `git.Repo()` so that
`backport_pr.py` can be called anywhere within the RIOT git repo
without manually passing the repo root path via `--gitdir`.

Previously the tool had to be called from the RIOT base repo.
