Panic on txn with value > 21mill in ChannelMonitor::block_connected

full_stack_target found a crash where we may overflow ruring fee
calculation if a transaction appears on-chain with massive value
available for us to claim. Since these transactions are clearly
bogus, we shouldn't allow full_stack_target to connect them, but
we also improve the error generated by explicitly panicing on them.
