linux support: "Broken pipe" exception

[yalov]

Hello,

on Linux (Ubuntu 20.04 arm64), if the server tries to send something to an already closed client, there is an exception in the libpthread send() function.
I tried to try{} catch(...){} the block in the Scs::Socket::Send , but it did not catch the exception for some reason.

on windows the same code, the same cmake project do not have this exception.

There is the call stack below.
