Fix cross-compilation of Cargo

Regressed in rust-lang#144303. I guess this wasn't seen in other `ToolTarget` tools, because they are more dependent on the compiler and are ~always built together with other stuff that also built the std, while Cargo is relatively self-contained.

Fixes: rust-lang#145059

Fix Cargo cross-compilation (take two)

In rust-lang#145083, I fixed the case of manually invoking `x dist cargo`, but I realized that `x install` creates the `tool::Cargo` step through the `from_build_frompiler` constructor, which doesn't go through `get_tool_target_compiler`. So we just prepare both the host and target stdlibs directly before building Cargo. Ideally we would get rid of `from_build_compiler`, but that will require refactoring the dist and test steps, which is upcoming.

Hopefully fixes rust-lang#145059 for good.
