Allow tolerance on compressed texture verification

Qualcomm GPUs are apparently decoding textures with a lower precision,
resulting in some of the rendered values when verifying the texture in
a test to be off by +-1 on any given channel. This change adds a
tolerance to those tests to allow a little wiggle room, since compressed
textures are inherently lossy anyway.

Allows Qualcomm GPUs to pass all compressed texture end2end tests.
