QRasterBackingStore: check format alpha presence in a more generic way
...instead of hardcoding a format such as ARGB32_Pre. A subclass may
override format() after all.
A few lines below there is the same check in fact, but this time
with hasAlphaChannel(). To be consistent, switch over to
hasAlphaChannel() in the first case as well.
Pick-to: 6.6 6.5
