provide more useful error message when running kpropd on command line
The way kpropd indicates that it's supposed to be connected to the network
is by printing out a socket error:
kpropd: getpeername: Socket operation on non-socket
With this patch, it's a bit more friendly:
./kpropd: Standard input does not appear to be a network socket.
(Not run from inetd, and missing the -S option?)
