i965: Fix gl_SampleMaskIn[] in per-sample shading mode.
The coverage mask is not sufficient - in per-sample mode, we also need
to AND with a mask representing the samples being processed by the
current fragment shader invocation.
Fixes 18 dEQP-GLES31.functional.shaders.sample_variables tests:
sample_mask_in.bit_count_per_sample.multisample_{rbo,texture}_{1,2,4,8}
sample_mask_in.bit_count_per_two_samples.multisample_{rbo,texture}_{4,8}
sample_mask_in.bits_unique_per_sample.multisample_{rbo,texture}_{1,2,4,8}
sample_mask_in.bits_unique_per_two_samples.multisample_{rbo,texture}_{4,8}
