curl needs --retry-all-errors

Verification

• I searched for recent similar issues at https://github.com/rust-lang/rustup/issues?q=is%3Aissue+is%3Aopen%2Cclosed and found no duplicates.
• I am on the latest version of Rustup according to https://github.com/rust-lang/rustup/tags and am still able to reproduce my issue.

Problem

"Connection Reset By Peer" is by-default treated as a fatal error by curl, but can be produced spuriously, either due to switching networks, or overly aggressive load-balancing by ISPs.

Steps

1. use rustup, then switch between wifi connections.

@lolbinarycat Thanks for filing this issue!

However, I am not quite sure whether you referring to the rustup-init.sh part or the Rust part of the software... If it's the latter then we have two download backends to choose from, did you mean the libcurl backend specifically?

In other words, would you mind explaining more about when you usually encounter this error?

Many thanks in advance 🙇‍♀
