channeldb: also ignore the EOF error when trying to read ExtraOpaqueBytes

Browse source 
In this commit, we account for the additional case wherein the
announcement hasn't yet been written with the extra zero byte to
indicate that there aren't any remaining bytes to be read. Before this
commit, we accounted for the case where the announcement was written
with the extra byte, but now we ensure that legacy nodes that upgrade
will be able to boot properly.
