Fixed bug 5335 - enable joystick/haptic/evdev support by default on FreeBSD

Alex S

Evdev headers aren't actually included in the base system (well, it has a private copy), they are available through the devel/evdev-proto port instead. We also have devel/libinotify and devel/libudev-devd shims, I didn't verify whether they work with SDL.
