Add the SO_REUSEADDR flag to sockets handled by netsock.  This is needed by
the patch that went in for issue 7874.  chan_iax2 needs to be able to create
socket that is lisetning on INADDR_ANY, but also be able to bind sockets to
specific addresses.  (Thanks to Stevenson on the asterisk-dev mailing list
for explaining why this flag was needed.)
