QColor: write signed 64-bit integer in a platform-independent way

When building Qt 5.6.2 with gcc 4.1.2 on Fedora 8, a compilation error
happened when compiling the code below
QColor::name()
{
...
   case HexArgb:
       return QLatin1Char('#') + QString::number(rgba() | 0x100000000, 16).rightRef(8);
...
}

qtbase/src/gui/painting/qcolor.cpp:527: error: integer constant is too large for ‘long’ type

gcc 4.1.2 was unable to handle 0x100000000. The patch is to use Q_INT64_C to
append "LL" to 0x100000000 to avoid the compilation error.
