bencodetools,uade: Fix build, update, modernise

[OPNA2608]

Addresses the bencodetools build failure on Hydra, which started after Python got bumped to 3.11 (https://hydra.nixos.org/build/275774889) + general maintenance & update stuff.

• bencodetools
  • Drop the python module building from the main package, which gets rid of the error
  • nixfmt it
  • Update src.hash format, get rid of meta-wide with lib
  • Update to latest stable version, add passthru.updateScript
  • Migrate it to pkgs/by-name
  • Re-init the python module as a separate python3Packages entry, inheriting lots of details from the main bencodetools package but only building the python module
• libzakalwe
  • init (needed for newer uade)
• uade
  • Drop the python tools building. It was already disabled on Darwin due to them not working there, but now that python doesn't like python setup.py install anymore, it just doesn't install anymore.
  • nixfmt it
  • Modernise
    • rec -> finalAttrs
    • --replace -> --replace-fail
    • Use lib.strings.withFeature
    • Get rid of meta-wide with lib
  • Update to latest stable version, add passthru.updateScript
  • Migrate it to pkgs/by-name
