Fix dEQP-VK.glsl.opaque_type_indexing.ssbo*_compute validation error

Tests were not checking maxPerStageDescriptorStorageBuffers limits
in the compute shaders, which use more (6) than the minimum limit
set by the spec for that (4).

Components: Vulkan
VK-GL-CTS issue: 3137

Affected tests:

	 dEQP-VK.glsl.opaque_type_indexing.ssbo*_compute
