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.
