[Piglit] [PATCH] arb_shader_image_load_store: Create complete textures.

[Dorian Apanel]

From: Dorian Apanel <dorian.apanel+piglit at gmail.com>

Textures created by image load/store tests are not complete (max level defaults to 1000).
Load/Store on incomplete textures should return zeros/change nothing.
This fix sets proper base and max level of textures.
