User mode "C": Allow messages from servers, services, and IRC Ops

Update user mode "C" handling ("Only users that share a channel are
allowed to send messages") to behave like user mode "b" ("block private
messages and notices") and therefore allow messages from servers, services,
and IRC Operators, too.

Change proposed by "wowaname" in #ngircd, thanks!
