Make QFreetypeFace::getFace() not return the same font
face for all memory fonts.
QtFreetypeData has a cache which maps QFontEngine::FaceId
to QFreetypeFace instances. Each FaceId should then
have a unique hash value, which is accomplished by
by hashing the font file name and a stored uuid.
However, we were not setting the uuid in all cases,
which means that in-memory fonts (which do not have
a file name) would hash identically.
Fix this by setting the uuid to a value based on the
address of the FontFile, which should be unique.
