Define EV_SET() for kqueue() on systems that don't have it

Some systems, notably FreeBSD 4.x, do have the kqueue() function but
lack the definition of EV_SET() in their header files -- but don't
worry, we can #define it on our own ;-)

Definition taken from /usr/include/sys/event.h of FreeBSD 8.1.
Patch tested on FreeBSD 4.1 by Götz Hoffart. Thanks!
