ext_mod: Fetch dependencies from hex.pm when mix is available

Browse Source 
This doesn't work when running an OTP release build using mix,
which means it doesn't work in binary installers or containers;
only when using relive, or compiled with rebar3.

Set the desired hex package version in the module's rebar.config
For example, to fetch hex package recon 2.5.5 when mix is available,
and otherwise download using git: in the file
  ejabberd-contrib/ejabberd_observer_cli/rebar.config
set both the hex version and git details:
{deps, [
        {recon, "2.5.5", {git, "https://github.com/ferd/recon"}}
       ]}.
