Add architecture (and revision) to the packages

[afbjorklund]

Currently we truncate the filenames, to make it "easier" for users:

• minikube_1.6.2.deb
• minikube-1.6.2.rpm

We should stop doing this, and use the real filenames instead.

• minikube_1.6.2-0_amd64.deb
• minikube-1.6.2-0.x86_64.rpm

This will make things less weird, when we support additional architectures...

• minikube_1.6.2-0_arm64.deb
• minikube-1.6.2-0.aarch64.rpm

For the raw minikube binary, we already include "-linux-amd64" in the filename.

---

The release is kept as 0, in case any distributions start packaging minikube...

• revision: https://www.debian.org/doc/debian-policy/ch-controlfields.html

• release: http://ftp.rpm.org/max-rpm/s1-rpm-build-creating-spec-file.html

And we still need to provide a real repository (apt, yum) for the vendor packages.

• apt: Make minikube (and kvm2) installable with "apt" #3110

• yum: Make minikube (and kvm2) installable with "yum" #4716

It's not like anyone wants to look after versions and architectures, but instead do:

• sudo apt install minikube

• sudo yum install minikube

The same goes for the docker-machine-driver-kvm2 packages.
