[PATCH 2/2] cargo.eclass: use direct CDN urls for crates.io

There are four reasons for doing this:

- it is the destination of a redirect at the urls we previously used, so
  less work

- per https://blog.rust-lang.org/2024/03/11/crates-io-download-changes/
  the API is "slow and expensive" and cargo now uses the CDN directly,
  too; all third-party "build systems" are recommended to do so as well

- crates.io/api has started banning download agents that don't suitably
  identify themselves, and curl/wget without --user-agent fail. This
  will also be fixed by https://github.com/gentoo/portage/pull/1585
  however that depends on users not manually setting FETCHCOMMAND
  with naive (no user-agent) values, nor using pk pkg env and
  copy/pasting.

- shorter urls *plus* lack of need for arrow renaming will nontrivially
  reduce the size of SRC_URI
