Fix packages broken by python-dateutil bump

[dotlambda]

Motivation for this change

All these applications are broken due to skarim/vobject#112.
For khal, there is also pimutils/khal#780.

An alternative would be to apply skarim/vobject#115 to the vobject package.

Note that papis doesn't build because pytest-httpbin is broken.
Also, I did not fix all applications that depend on vobject.

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Fits CONTRIBUTING.md.
