[PATCH] xfree86: set mask for valuators 0/1 when emulating core events (#30267)

[Peter Hutterer]

EventToCore as of the commit below won't generate core motion events if the
valuator mask for x/y isn't set. For DGA, we work around this check by
forcibly setting the mask in the event we pass down.

    dix: don't create core motion events for non-x/y valuators.
