EGL: eglChooseConfig returns num_config=0

Dear mesa-EGL developers,

I just updated to Fedora 30 [1] and I start to get an error message:

> Failed to initialize accelerated iGPU/dGPU framebuffer sharing: No
matching EGL configs

which happens because (see [2] for details) eglChooseConfig returns 0
matches. Is this expected to happen? 

My hardware has only one GPU: an Intel iGPU from the first generation
of Core i5 CPUs, i.e. Core i5-650. [3]

I've attached the standard output of `eglinfo`. It prints this line to
stderr though:

> i965_dri.so does not support the 0xffffffff PCI ID.


[1] with: mesa-egl 19.0.3, kernel 5.0.11, gnome-shell 3.32.1, mutter
