build-support/go: fix eval of `vendorSha256` accesses 

Before the change there was no way to poll for presence of
`vendorSha256` attribute:

    $ nix-instantiate --strict --eval --expr 'with import ./. {}; _3mux.vendorSha256 or "no hash"'
       error: attribute 'vendorSha256' missing
          292|     passthru = passthru // { inherit go goModules vendorHash; } // { inherit (args') vendorSha256; };
             |                                                                     ^

After the change the poll happens as expected:

    $ nix-instantiate --strict --eval --expr 'with import ./. {}; _3mux.vendorSha256 or "no hash"'
    "no hash"
