Update usocket.c

Browse Source 
In our application we find that under certain conditions, SIGPIPE signals the occur when socket is writing kills the process, even though the signal is ignored in the socket_open function.
I found that adding the SIG_IGN handler for the signal before each write call to the socket fixed the issue for us.
