[PATCH] Input: joydev - Recognize joysticks with Z axis as joysticks.

Current implementation of joydev's input_device_id
table recognizes only devices with ABS_X, ABS_WHEEL
or ABS_THROTTLE axes as joysticks.

There are joystick devices that do not have those axes,
for example TRC Rudder device. The device in question
has ABS_Z, ABS_RX and ABS_RY axes causing it not being
detected as joystick.

This patch adds ABS_Z to the input_device_id list
allowing devices with ABS_Z axis to be detected
correctly.
