amd-gpu-x11-bin: Add pkgconfig files for EGL and OpenGL ES 2
The pkgconfig files are need for some applications which use it to
check for library avaiability. The culprit which triggered it was the
addition of glmark2 into the test image, thus causing a build failure
in our autobuilder.
The build has been tested in X11 and Framebuffer backends.
