lib/igt_fb: Export the cairo surface instead of writing to a png

This removes the igt_write_fb_to_png function (that was unused thus far)
and exports the igt_get_cairo_surface function to grab the matching
cairo surface. Writing to a png is now handled by the common frame
handling code in lib/igt_frame.

This also fixes how the surface is retreived in chamelium code,
which avoids destroying it too early.
