Remove tests with test bugs from multisample configs
Test issues had resulted in some interpolate_at_centroid tests being removed from AOSP mustpass.
These were incorrectly not removed from the multisample mustpass lists.
Affects:
dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_centroid.consistency.default_framebuffer
dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_centroid.array_element.default_framebuffer
VK-GL-CTS issue: 993
