specs: Remove GLES profile interaction text from GLX_MESA_query_renderer

In one place we say, if GLES isn't supported then the profile version
will be 0.0. Then later we say, if the GLES profile extension isn't
supported then GLX_RENDERER_OPENGL_ES_PROFILE_VERSION_MESA is not
mentioned in the spec. A strict reading of the latter would mean that
GLX_RENDERER_OPENGL_ES_PROFILE_VERSION_MESA is not a recognized token,
and the query should instead return False.

The implementation does not check for the GLES profile extensions, and
the additional complexity doesn't seem worth it. Removing the
interaction text makes the spec match the implementation.
