Bump Rust toolchain to 1.41.0

lopopolo · lopopolo · commit c46d04c70621 · 2020-02-21T17:20:12.000-08:00
Rust 1.41.0 uses the upstream LLVM backend to build emscripten targets. This enables upgrading the `emscripten-toolchain` for building mruby to the latest upstream compiler. This replaces the fastcomp compiler dependency which had some optimizer bugs that caused crashes when compiling debug builds. (Debug builds still do not work - `regex_automata` segfaults rustc - see rust-lang/rust#69364.
