Allow more conservative coverage for degenerate triangles

Some implementations of conservative rasterization with degenerate
triangles produce more than one pixel worth of coverage, which is
allowed by the Vulkan specification.

This CL modifies the test to allow some extra coverage so it works
on these implementations.

Affects:

dEQP-VK.rasterization.conservative.overestimate.*.triangles.degenerate.*

Components: Vulkan

VK-GL-CTS issue: 2859
