Subject: [PATCH] rustPlatform.importCargoLock: use `cp -L` again, but ignore
 error

We accidentally broke the dereferencing logic of copying in https://github.com/NixOS/nixpkgs/pull/379049

The new solution is just to revert back to using `cp -L` but to also ignore the
non-zero exit code with the || operator
