Fix vivid build failure (older Qt)

Fix incorrect mouse wheel/touchpad scrolling scale (LP: #1607240)
and also add sufficient precision that high-resolution touchpad
scrolling now works! (LP: #1607223)

This fixes two mistakes:
 1. angleDelta is not in degrees but eighths of a degree, so the magic
    constant 15 should be 120 (QWheelEvent::DefaultDeltasPerStep)
    [http://doc.qt.io/qt-5/qwheelevent.html#angleDelta].
 2. When converting from Qt back into a Mir event we forgot completely
    to divide by the same factor to get back to the Mir scale of things.

Additional fixes required!
Unfortunately we've built an ecosystem with tweaked values to work with
the old incorrect scroll values and additional fixes are required after
this one:
  Xmir: Done, pending release in yakkety.
  System Settings: Default scroll scale should be 1.0, not 0.5 (which is
     the secret unlabelled scroll bar under 'Mouse & Touchpad').
  webbrowser and other Qt apps: Not sure where to do that but they scroll
     way too slowly with this fix and obviously need updating.

Implement MirSurface::inputBounds and make use of mir's input region

This allows us to finally drop the UbuntuKeyboardInfo hack.
