Reduce expected precision of RGB10A2 filtering

The code in the YCbCr tests says that it was copied from the texture
explicit lod tests, but those tests give rgb10a2 a 'low' precision, not
'fp16'. Reduce the precision expected in the YCbCr tests.

Components: Vulkan
VK-GL-CTS Issue: 1731
Affects: dEQP-VK.ycbcr.*
         dEQP-VK.protected_memory.interaction.ycbcr.*
