git-rebase--interactive.sh: Don't pass a strategy to git-cherry-pick.

git-cherry-pick doesn't support a strategy paramter, so don't pass one.
This means that --strategy for interactive rebases is a no-op for
anything but merge commits, but that's still better than being broken. A
correct fix would probably need to port the --merge behaviour from plain
git-rebase.sh, but I have no clue how to integrate that cleanly.
