glx: Enable GLX_EXT_create_context_es2_profile
This extension is only enabled if the underlying driver advertises support for OpenGL ES 2.0. This happens either through the getAPIMask function in version 2 of the DRI2 extension or implicity through version 2 of the DRISW extension. Since there is no OpenGL ES 2.0 protocol, this extension is marked as only available with direct-rendering. Signed-off-by: Ian Romanick <[email protected]>
