rHG7bd13bf99d1c: rust: update minimum supported Rust compiler version
Summary

Debian stable backported rustc 1.41.1 for a Firefox release that needed it,
so we can finally update the compiler version to something that isn't more than
a year old.

This means that (among other things [1]), async await syntax is usable!
