wayland-egl: Remove EGL_EXT_present_opaque from client extension list

   EGL_EXT_present_opaque is an EGL display extension, and was erroneously
   added to both the display extension list and the client extension
   list, causing a failure of the ES CTS on L4T's Jenkins server. This
   change removes it from the client extension list.
