sockfilt: make select_ws stop waiting on exit signal event
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). Reviewed-by: Jay Satiro Part of #5260
