Ignore Celo base fee floor after Jovian

[karlb]

We want to use Jovian's minBaseFee instead.

Hey @karlb looks like this PR got a bit mangled, maybe the base needs to be changed?

Yes, that happens when it is stacked on another PR and that one gets merged via squash or rebase. A highly annoying part of github that I only stumbled across a dozen times this year. 😠 I've rebased it, so it looks clean again.

How does the transition look? I assume with the given code it would be a step in the minimum base fee, which might lead to lots of rejected transactions.

Yes, it would be step greater than the usual maximum change between blocks. It would be nicer to increase it in small steps, but I don't see a really simple way to do it. And I don't think avoiding to drop a few txs is worth a much effort.

My preferred way would be to limit the minBaseFee change to the max change allowed per block, but that would be a deviation from upstream. I would only like to do that if upstream is likely to accept it.
