virtual-input/evdev: Translate from button internal codes to evdev

Sending button events to a ClutterVirtualInputDevice, the API expects
button codes to be of the internal clutter type. The evdev
implementation incorrectly assumed it was already prepared evdev event
codes, which was not the case. Fix the evdev implementation to translate
from the internal representation to evdev before passing it along to
ClutterSeatEvdev.
