This commit addresses an issue to enhance the resilience of core
lightning when receiving node announcements.
According to BOLT 7 (The announcement_signatures Message),
if the node_signature OR the bitcoin_signature is NOT correct,
it is recommended to either send a warning and close the connection or send an error and fail the channel.
In this commit, we take a strict approach. If any error is detected, we
send an error and fail the open channel operation.
This is because the announcement_signatures operation is optional,
and we assume that it must be correct.
lnprototest at commit dea47c29b5541dbfe7fe53cc2598330e897fa4f4 report
the following error now.
