[Piglit] [PATCH 2/6] arb_bindless_texture: add uniform-block-initializer.frag compiler tests

[Samuel Pitoiset]

"Replace Section 4.1.7 (Samplers), p. 25"

    "As uniforms in the default uniform block, samplers may be
     initialized only with the OpenGL API; they cannot be declared
     with an initializer in a shader."

"Replace Section 4.1.X, (Images)"

    "As uniforms in the default uniform block, images may be
     initialized only with the OpenGL API; they cannot be declared
     with an initializer in a shader."

Just to be sure samplers/images are not too relaxed when bindless
texture is enabled.
