Expand the OpenGL related error messages we produce for various
"OpenGL not present/not supported" cases, to hopefully guide the
user towards how to fix things.
Now if the user tries to enable GL on a backend that doesn't
support it the error message is a bit more precise:
$ qemu-system-aarch64 -M virt -device virtio-gpu-gl -display curses,gl=on
qemu-system-aarch64: OpenGL is not supported by display backend 'curses'
