dbus-sharp-2_0: fix build

[worldofpeace]

This is a reported issue which is fixed either by downgrading mono or by using msbuild.
The use of msbuild would have been preferred here if it was in nixpkgs.

Motivation for this change

This build failure

Failure adding assembly dbus-sharp.dll to the cache: Strong name cannot be verified for delay-signed assembly

ZHF: #45960

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.

a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowUnsupportedSystem = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowUnsupportedSystem = true; }
to ~/.config/nixpkgs/config.nix.

tomboy failure looks unrelated, mono-addins doesn't build.

[worldofpeace]

Another for me squash in the ZHF then 😆

[xeji]

LGTM, just one comment for the next person looking at this...

[worldofpeace]

Hmm mono-addins fails with this same error.
This fix will be in a few other places then.
