This commit simplifies the goreleaser configuration and then adds nfpm
support which allows us to build .deb and .rpm for each of the ARCH we
support.
The deb and rpm packages adds systemd services and users, creates
directories etc and should in general give the user a working
environment. We should be able to remove a lot of the complicated,
PEBCAK inducing documentation after this.
