udev: consider a device with BTN_TRIGGER_HAPPY as joystick
These buttons were added specifically for joysticks with lots of buttons, no
other device should be using them. See kernel commit
cf2f765f18960 "HID: handle joysticks with large number of buttons"
We only test for BTN_TRIGGER_HAPPY (an alias for BTN_TRIGGER_HAPPY1) here, a
device that sets buttons 2 and above but doesn't set 1 is considered buggy.
