mesa/main/version: Lower the requirements for GLES 3.0

GLES 3.0 does not actually require support for EXT_framebuffer_sRGB, it
only needs support for sRGB attachments to framebuffers and framebuffer
objects as defined in ARB_framebuffer_objects.

v2: Clarify that ARB_framebuffer_objects is needed.
