[Mesa-stable] [PATCH v2] egl/dri2: expose srgb configs when KHR_gl_colorspace is available

[Emil Velikov]

Otherwise the user has no way of using it, and we'll try to access the
linear one.

v2:
 - Bail out when KHR_gl_colorspace is missing and srgb is set (Marek)

Mauro, I thought you already tested this but I cannot find any traces.

Thanks
