aux/socket: patch scheduling bug in socket egg

It's possible for the thread to be interrupted between configuring the
timeout and the file descriptor wait. This causes a low-probability 60
second wait until the timeout expires.

Now that this is fixed, we can set a normal timeout on the socket once
again, so do that.
