enable building rpm and deb through github actions

[flowpoint]

Hi there,
it seemed like there aren't yet packages for the podman driver.
it would be a nice to have in your yum and deb repos, like https://rpm.releases.hashicorp.com/fedora/hashicorp.repo](https://rpm.releases.hashicorp.com/fedora/hashicorp.repo)

i hope this pr is a start.
this might also be a solution for #176

i tried to match your release setup from the nomad repo.
however, hashicorp/actions-packaging-linux expects there to be a binary and installs it only /usr/bin.
i lifted this requirement in my temporary fork, see: flowpoint/actions-packaging-linux and opened hashicorp/actions-packaging-linux#7

comments appreciated
greetings

Hi @flowpoint 👋

Thanks for the PR! We currently don't package any of our plugins, but it's an interesting suggestion. I think it would require some sort of standardization and coordination to make sure all plugins are installed the same way. I will discuss it with the rest of the team.
