In a subsequent commit, we will allow the counterparty's dust limit to be greater than our `MIN_THEIR_CHANNEL_RESERVE_SATOSHIS`. Our selected reserve must always be greater than their dust limit, so we set our selected reserve to be equal to or greater than their dust limit.
This includes both keyed anchor channels, and 0FC channels. The dust limit for HTLCs in such channels is independent of the negotiated feerate, so a party may set a higher dust limit for such channels. Fixes lightningdevkit#4225
