cairo: fix the eval on `mingwW64`

In https://github.com/NixOS/nixpkgs/issues/456516
user reported eval fails as:

    $ nix build --no-link -f. pkgsCross.mingwW64.cairo
    error:
       … while calling the 'derivationStrict' builtin
         at «nix-internal»/derivation-internal.nix:37:12:
           36|
           37|   strict = derivationStrict drvAttrs;
             |            ^
           38|

             |           ^
          825|         }

       (stack trace truncated; use '--show-trace' to show the full, detailed trace)

       error: Unknown value for ipc_rmid_deferred_release

The change will not fix `caori` build on `windows`
but at least will report unsupported dependencies.
