[igt-dev] [PATCH i-g-t] Dockerfile: Avoid touching external resources

[Arkadiusz Hiler]

Let's install all the necessary things in the build-* images, so we
don't touch/hammer external servers each time there is a small change in
IGT.

We have already seen this failing:

	Error: Error downloading packages:
	  Status code: 503 for https://mirrors.fedoraproject.org/metalink?repo=fedora-30&arch=x86_64
	The command '/bin/sh -c dnf install -y findutils &&         dnf clean all' returned a non-zero code: 1
