feat(package): Add RPM, deb, pacman and tar packages and manpage

Build package using fpm. As I don't want ruby/gem in my computer, the
build system creates an OCI image with Podman (at this time), and
generate dist pacakges.

To enhance the packages, a manpage is now generated from the
documentation.
