svga: fix the test for sRGB texture formats

The pipe_sampler_view::format field should be prefered over the resource/
texture format.  The former is used to override the texture format for
sRGB decode enable/disable, etc.

Also, use new util_format_is_srgb() helper to catch all sRGB formats.

This fixes the piglit tex-srgb test for GL_EXT_texture_sRGB_decode.
