ci: split aws credentials in two separate users with scoped perms

This commit changes our CI to use two separate IAM users to
authenticate with AWS:

* ci--rust-lang--rust--sccache: has access to the rust-lang-ci-sccache2
  S3 bucket and its credentials are available during the whole build.
* ci--rust-lang--rust--upload: has access to the rust-lang-ci2 S3 bucket
  and its credentials are available just during the upload step.

The new tokens are available in the `prod-credentials` library.
