Remove incorrect check in qpixmap autotest.

The test assumed that pixmaps do not have an alpha channel. This is
not true on some platforms, e.g. Symbian with OpenVG, there pixmaps
are often backed by some image data in ARGB32_Premultiplied format,
which means that QPixmap::mask() will return a valid QBitmap.
