Fix uninitialized value warning in QFontEngineFT.
When running an application which called e.g. QPainter::drawText under
Valgrind, it would produce "Conditional jump or move depends on
uninitialized value(s)" warnings, since we were allocating a buffer for
a FreeType bitmap without initializing its contents. FreeType,
apparently, does not set the value of all bytes in a bitmap buffer when
it is used as a FT_Bitmap, so we were left with some uninitialized
memory which was still being used.
This commit fixes these warnings, and prevents any potential undefined
behavior.
[ChangeLog][QtGui][General] fixed use of uninitialized memory in the
FreeType font engine
