Fix rbt land --squash when landing a review request.
Review Request #11296 — Created Nov. 21, 2020 and submitted
rbt land --squashwas correctly squashing commits when landing a local
branch, but not when loading a review request with multiple commits. All
the work to handle squashing a patch was already done, but we just
weren't plumbing the
rbt patchto trigger it.
This is a simple change that adds the missing argument, fixing squashing
of multi-commit review requests.
