Test native graphics engine in tst_QGlyphs

Drawing to QImage will always go through the raster engine, so some
bugs might not be caught. This also fixes a test failure on X11,
since the raster engine on X11 is inconsistent with regards to
how it handles subpixel antialiasing into images. See task
QTBUG-11268.
