[Piglit] [PATCH 9/9] arb_shading_language_420pack: Adds multiple layout qualifiers in a single buffer declaration tests

[Andres Gomez]

Added tests to check that all the layout-qualifier-ids in more than
one layout-qualifier in a single non-variable buffer declaration are
taken into account.

The tests check that this works for non-value layout-qualifier-ids. So
far, there is no value layout-qualifier-ids with which to check.

>From the ARB_shading_language_420pack spec:

    "More than one layout qualifier may appear in a single declaration."
