Subject: [PATCH 1/2] venator: fix build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This probably wasn’t caught because, once `cargoHash` was generated,
`venator.cargoDeps.vendorStaging` would have needed to be rebuilt to
catch the failure.

Moving `Cargo.lock` in `postPatch` is ineffective because `postPatch` is
not passed to `fetchCargoVendor`. Removing `cargoRoot` is the simpler
solution.
