Increase the tolerance in test_texture_compressed_3d().

I get the same results for d3d10core:c3d10core and d3d11:d3d11.
In both cases increasing the tolerance to 4 is not sufficient:

4:
d3d10core.c:19081: Test failed: Got unexpected colour 0xff00003b at (2, 240,
9), expected 0xff000040.
5:
d3d10core.c:19081: Test failed: Got unexpected colour 0xff000048 at (2, 32,
12), expected 0xff00004e.
6:
d3d10core.c:19081: Test failed: Got unexpected colour 0xff000057 at (2, 160,
14), expected 0xff00005e.

With a tolerance of 7 there is no failure anymore, at least on Windows 10 1507
with the 391.35 driver. So if rounding that to 8 is acceptable then the
attached patch could fix this issue in both cases.
