Ryan Artecona 4183604207 elixir: fix mix on darwin
Darwin disallows shebang scripts from using other scripts as their
command--the command must be a binary. This commit changes the `mix`
shebang script from calling `elixir` directly (another shebang script),
instead using `env` as an intermediary.

Fixes #9050

longDescription = ''
Elixir is a functional, meta-programming aware language built on
top of the Erlang VM. It is a dynamic language with flexible
syntax and macro support that leverages Erlang's abilities to
build concurrent, distributed and fault-tolerant applications
with hot code upgrades.
