distro/pkg/deb: deep clean Debian packaging with pedantic lintian

I've used apkg lint --pedantic to eliminate all lintian --pedantic --display-info cries.

Amongst other things, I've changed from manual meson/ninja invocation to using it through debhelper with --buildsystem=meson.

Only one last info message regarding python/knot_resolver/utils/modeling/README.md is left:

I: knot-resolver6: package-contains-documentation-outside-usr-share-doc [usr/lib/python3/dist-packages/knot_resolver/utils/modeling/README.md]
N: 
N:   This package ships a documentation file outside /usr/share/doc Documentation files are normally installed inside /usr/share/doc.
N:   
N:   If this file doesn't describe the contents or purpose of the directory it is in, please consider moving this file to /usr/share/doc/ or
N:   maybe even removing it. If this file does describe the contents or purpose of the directory it is in, please add a lintian override.

added packaging label

I think this is ready to merge.

To be continued with rpm cleanup and possible lint jobs in another MR.

Overall this MR looks "safe" to me. The comment above is the only point I noticed that might be worth considering.
