[Piglit] [PATCH 17/18] shader_runner: Fix texture rgbw on GLES.

[Francisco Jerez]

GLES2 (and potentially also GLES3 depending on the internal format)
doesn't allow the specification of a texture image with base format
GL_RGBA and type GL_FLOAT, as piglit_rgbw_texture() would attempt to
do when the specified basetype argument is GL_UNSIGNED_NORMALIZED.
GL_UNSIGNED_BYTE should be okay though according to table 3.4 of the
GLES2 specification.
