winex11.drv[1/6]: wintab: copy also the button #0 state

[Mikolaj Zalewski]

>From this series the first two patches fixes wintab so that a tablet
works with Photoshop 6-CS1 on my laptop. However I'm not an XInput
expert so I'm not sure they are correct. The patches 3-6 should be
independent from them and implement Unicode support in wintab32.

This patch copies the state bit #0 to the wintab client. As least on
my setup this bit represent the pressure button - a button that is
activated when the stylus contacts with the tablet and which state is
also reported by Windows wintab32. Without the information that this
button is pressed Photoshop will ignore the tablet data. The
WM_MOUSEDOWN will be still received so Photoshop will draw but as if
there was a maximal pressure.
