Unrolled build for #145000

Rollup merge of #145000 - Kobzol:std-cargo-stage, r=jieyouxu

Remove unneeded `stage` parameter when setting up stdlib Cargo

The standard library can't be built using a compiler that has a lower stage than 1 anymore, so the condition was useless (you can test that with e.g. `x doc std --stage 0`, which is broken - I aim to forbid doing that soon).

Found this while doing an unrelated cleanup.
