Gracefully handle fee-larger-than-claimed-value in ChannelMonitor

This resulted in a full_stack_target failure as we overflow during
subtraction otherwise.

Instead, we try lower and lower fee estimator confirmation targets
until we find one low enough, or discard the transaction. We should
be able to handle this much cleaner, but for now this at least gets
the fuzzer working again.
