xcb: Show valuator atom names properly in categorized logging 

During a touch update, this looked questionable since I don't have any
barcode readers or buttonboxes attached:

XI2 touch event type 19 seq 1481 detail 193 pos  116.3,   77.8 root pos 6476.3, 2941.8 on window 3e00006
   valuator              BARCODE value 47796.365791 from range 0.000000 -> 65535.000000
   valuator            BUTTONBOX value 59504.858830 from range 0.000000 -> 65535.000000
   touchpoint  193  state  QEventPoint::Updated  pos norm  QPointF(0.729326,0.907986)  area  QRectF(...

After the fix it's like this:

XI2 touch event type 19 seq 1235 detail 201 pos  154.0,   64.3 root pos 6168.0, 2794.3 on window 5000006
    valuator    Abs MT Position X value 45520.589958 from range 0.000000 -> 65535.000000
    valuator    Abs MT Position Y value 56519.790001 from range 0.000000 -> 65535.000000
    touchpoint  201  state  QEventPoint::Updated  pos norm  QPointF(0.6946,0.862437)  area  QRectF(...

ValuatorClassInfo's QXcbAtom::Atom is a Qt enum, which has to be
converted to xcb_atom_t before we can call xcb_get_atom_name_name.
Originally in ce2fe90faa vci was of type
XIValuatorClassInfo; then 7499d4404f
changed it to our ValuatorClassInfo struct, but didn't add the lookup
indirection to this qCDebug.

Pick-to: 5.15 6.2 6.3
