elixir: Update to 1.11.1

"Over the last releases, the Elixir team has been focusing on the compiler, \ 
both in terms of catching more mistakes at compilation time and making it \ 
faster. Elixir v1.11 has made excellent progress on both fronts. This release \ 
also includes many other goodies, such as tighter Erlang integration, support \ 
for more guard expressions, built-in datetime formatting, and other calendar \ 
enhancements."
