[Piglit] [PATCH] glsl-1.30: Only require gl_MaxTextureUnits >= 2

[Ian Romanick]

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

Note that the minimum maximum should is 2, but it is incorrectly
listed as 16.  This was fixed in GLSL 1.50 (see page 75 (page 81 of
the PDF)), but the fix was never back ported to 1.30 or 1.40.
