Suppressed warnings from failed stream_socket_accept()

FastCGIDaemon v0.5.3

Fixes

• Suppressed stream_socket_accept warnings. Was getting: "stream_socket_accept(): accept failed: Resource temporarily unavailable" despite waiting until a read was ready using stream_select. This only happened using mod_fastcgi on Apache with multiple processes (rather than one worker). It looks as if the connections were closed before they could be accepted - from the client side, all of the requests were answered correctly without server errors so I'll suppress these warnings for now.
