tinyjpeg: Better luminance quantization table for Pixart JPEG

An other luminance quantization table gives a better quality to the
Pixart images created by the webcams handled by the gspca drivers
pac7302 and pac7311 (pixel format 'PJPG').

Tests have been done with 5 different pac7302 webcams. The marker was
always 0x44.
