Input: wacom - add device type to device name string

Devices supporting both pen and touch features share the same product ID,
but presented as 2 separate input devices. By adding device type to device
name string we can help userspace applications and users differentiate
between them. 'Finger' is used for the touch since touch has been used as
a suffix by userland hotplugging services.
