pvr: Increase maxVertexOutputComponents limit for zink

Browse source 
Zink reserves up to 60 varyings components for streamout which
requires a maxVertexOutputComponents of at least 128 to avoid the
exposed value for GL_MAX_VARYING_FLOATS been below the minimum value
for GLES3.0

Fix for the follow gles cts tests:
dEQP-GLES3.functional.state_query.integers.max_varying_components_getfloat
dEQP-GLES3.functional.state_query.integers.max_varying_components_getinteger64
dEQP-GLES3.functional.state_query.integers.max_varying_vectors_getfloat
dEQP-GLES3.functional.state_query.integers.max_varying_vectors_getinteger64

Backport-to: 26.0
