glsl: Drop resize-to-MaxPatchVertices hack.

TCS and TES inputs without an array size are implicitly sized to
gl_MaxPatchVertices.  But TCS outputs are apparently not:

   "If no size is specified, it will be taken from the output patch size
    (gl_VerticesOut) declared in the shader."

Fixes dEQP-GLES31.functional.program_interface_query.program_output.
array_size.separable_tess_ctrl.var.
