Add rpkg template for COPR autobuild

This commit removes .autocopr/podman.spec in favor of
podman.spec.rpkg to account for new recommendations for COPR builds.

The build process now enables debug packages and also uses
`%gobuild` instead of `make` or `go build` to
get the packages as close as possible to Fedora koji builds.

-%{name} (Pod Manager) is a fully featured container engine that is a simple
-daemonless tool.  %{name} provides a Docker-CLI comparable command line that
-eases the transition from other container engines and allows the management of
-pods, containers and images.  Simply put: alias docker=%{name}.
-Most %{name} commands can be run as a regular user, without requiring
-additional privileges.

-%{name} uses Buildah(1) internally to create container images.
-Both tools share image (not container) storage, hence each can use or
-manipulate images (but not containers) created by the other.
