[Piglit] [PATCH] program_interface_query: don't expect a valid location for TCS output

[asimiklit.work at gmail.com]

From: Andrii Simiklit <andrii.simiklit at globallogic.com>

I guess we should not expect a valid location for:
"patch out vec4 tcs_patch;"
because this output variable is declareted
without "layout (location=X)" and according to spec:
   "Not all active variables are assigned valid locations; the
    following variables will have an effective location of -1:

      * uniforms declared as atomic counters;

      * members of a uniform block;

      * built-in inputs, outputs, and uniforms (starting with "gl_"); and

      * inputs or outputs not declared with a "location" layout qualifier,
        except for vertex shader inputs and fragment shader outputs."

Also I fixed some conflicting comments.
