Bug 1324040 - mozboot: Download rustup without SNI. r?froydnj
It seems older Python (e.g. 2.7 from Ubuntu 14.04) doesn't
support SNI, so we get a TLS error with the canonical
https://static.rust-lang.org/ url even when using the
`requests` module.
Fall back to the no-CNAME host instead which is ugly but works.
Thanks to Simon Sapin for the suggestion.
