[Piglit] [PATCH] arb_explicit_location: Add tests without the extension enabled

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

Make sure that the correct error is generated.  The second 1.30 version
and the 1.40 of the test ensure that layout() exists at all by using a
different extension (or GLSL version).
