QCommonStyle: work around apparent MSVC bug in using QFlag

Browse Source 
With the upcoming change to QFlags to support 64-bit, MSVC started to
complain that it can't convert from Qt::Alignment to QFlag and back to
Qt::Alignment. It is correct that this path has an explicit and
shouldn't be taken, but
 a) it's worked for years
 b) GCC and Clang insert an extra conversion to int (I guess)

In any case, header->iconAlignment is already a Qt::Alignment so we
don't need to go through QFlag here.

qcommonstyle.cpp(1666): error C2440: '<function-style-cast>': cannot convert from 'const Qt::Alignment' to 'QFlag'
qcommonstyle.cpp(1666): note: Constructor for class 'QFlag' is declared 'explicit'

Pick-to: 6.8
