Core/Sockets: Always try to send MSG_NOSIGNAL in peer().send()

Browse Source 
Fixes RASocket::authenticate crash

"MSG_NOSIGNAL:
If you send() to a remote host which is no longer recv()ing, you'll typically get the signal SIGPIPE. Adding this flag prevents that signal from being raised."

Closes #5040
Thanks to @derex for the hint
