Revert "Update cargo"

[Mark-Simulacrum]

This reverts commit 331aa45.

This Cargo upgrade introduced a regression into dependency resolution, so reverting the upgrade until we can fix that.

@bors r+ p=30

Going to self-approve this revert since it's literally just undoing a previous change and I want to minimize the chance of this hitting nightly later today (since it seems like it would break lots of builds in practice, unless I'm missing something obvious).

Filed rust-lang/cargo#11330 to track fixing it.
