Rust plugin using old rustup link

[Chris Holcombe]

The rust snappy plugin is now using an older version of rustup. The project has been moved to https://rustup.rs. I'll file a PR to fix this

While we are on it, would it make sense to get rustup snapped? We should
professionalise that curl | sudo bash part ;)

Yeah I think that gets me out of the jam. When rustup was migrated from a bash script over to a rust binary it lost the ability to be installed in a prefix directory. Installing from a snap would resolve that problem. It would also resolve the issue of having to choose the right binary for the architecture being used.
#snappy said to watch this bug https://bugs.launchpad.net/snapcraft/+bug/1616985. They're going to do a similar thing where they install a snap to help the plugin complete its work.

I'm suspecting this is no longer in progress?

The address https://static.rust-lang.org/rustup.sh now has a 301 redirect to https://sh.rustup.rs/
 so this issue was fixed by itself. However, now that snapcraft uses the new rustup it comes with different command line arguments and causes #1809259.
