Added ExitedEvents for links whose sockets fail on creation.
When we try to link to a remote process, we will send the linkee an
`ExitedEvent` when the link is broken or if the connection fails.
This patch adds an `ExitedEvent` when the socket creation step fails.
This is logically equivalent to having the connection step fail.
Because this is an entirely unexpected case, the log level should be
a WARNING or higher.

> Noticed this while inspecting nearby code for potential races.
> Normally, when a libprocess actor (the "linkee") links to a remote process,
> it does the following:
> 1) Create a socket.
> 2) Connect to the remote process (asynchronous).
> 3) Check the connection succeeded.
> If (2) or (3) fail, the linkee will receive a {{ExitedEvent}}, which
> indicates that the link broke. In case (1) fails, there is no
> {{ExitedEvent}}:
