Add a new option to conditionalize xconv installation

xconv is the only piece of xinetd written in perl, removing it from package
also removes perl dependency.

Add a new option, on by default to don't change current behavior, to select
to install or not xconv.

While here, re-generate patches using `make makepatch` to silence portlint
