remove unnecessary beginPaint and endPaint overrides

QPlatformBackingStore::endPaint does not take a QRegion parameter.
6ce6b8a378b0d97ba950240ffb048a4b7e485235 set the API, but the
platform implementations were not all synced up since then.  There
was anyway no point in overriding beginPaint and endPaint on
platforms which don't need to do anything there.  This fixes
clang warnings of the form
QXcbBackingStore::endPaint hides overloaded virtual function
