sockfilt: make select_ws stop waiting on exit signal event

Browse Source 
This makes sure that select_ws behaves similar to real select
which stops waiting on a signal handler being triggered.

This makes it possible to gracefully stop sockfilt.exe on
Windows with taskkill /IM sockfilt.exe (without /F force flag).
