Require sampleRateShading in multisample linear interpolation tests

While these tests normally set sampleShadingEnable to VK_FALSE, their
shaders enable the SampleRateShading capability, which means
sampleRateShading is required to run them.

Affects:
dEQP-VK.draw.*.linear_interpolation.*

VK-GL-CTS issue: 4167
Components: Vulkan
