Podman image: Mass cleanup + fix missing storage.conf

As of Fedora 36, `/etc/containers/storage.conf` with defaults is
installed under `/usr/share/containers/`.  This was causing builds
to fail in the necessary `sed` command that enables fuse-overlayfs.
Fix this by using sed on the new location with an output redirect
into the `etc` location.

Also, perform a mass-cleanup of the three files to make them easier
to read/maintain.  Including renaming them to `Containerfile`,
since all native build tooling is now used to produce them.

Lastly, take advantage of the `podman-next` copr repository to install
the latest/greatest podman from `main`, rather than building it from
scratch.  This will greatly speed up the image build speed.
