Add support for OpenBSD 

There were three patches OpenBSD applied to build Irrlicht, and I implemented two of them. The first required turning off joystick events on OpenBSD, and the second (which I didn't confirm was necessary) required some defines in os.h. The third patch would have added an include to CIrrDeviceLinux.cpp, but the file had changed quite a bit and I could not tell whether this was necessary, so I left it out, and it appears Irrlicht builds fine.
