Switch to use diener patch for companion build

[bkchr]

This switch to the new diener patch command to patch all Substrate
crates in Polkadot. This should remove the requirement to manually merge
Substrate master to make the companion build, as we now would use the
already with master merged code from this build job local checkout.

We already have diener installed in the CI image. I suggest just bump the version there instead of installing it again, over and over.

Can we do this in a non-breaking way? The problem is that this new version isn't compatible with the old one. And I'm aware that we have installed it in the CI image. My idea was to update it here first, wait some days and update the CI image after this.

CI image is updated every night (unless it's blocked by something else I.e. in substrate tests).
Ok, I got you, will do this after I'm back from vacation.
