Add native-deb* targets to build native Debian packages

In continuation of previous openzfs#13451, this commits adds native-deb*
targets to build native debian packages and updates the Github
workflows to build and test native packages on Ubuntu 20.04.

Ubuntu 18.04 workflow would still build and test the Alien
converted Debian packages due to unmet build and install
dependencies.

Native packages only build with pre-configured paths (see the rules
file). Initial config flags e.g. '--enable-debug' are passed to
contrib/debian/rules.

Additional packages on top  ofexisting zfs packages required to
build native packages include debhelper-compat, dh-python, dkms,
po-debconf, python3-all-dev, python3-sphinx.

For release, contrib/debian/changelog should be updated with release
version.
