New "make relive" similar to "ejabberdctl live" without installing

Prepare with:
  ./autogen.sh && ./configure --with-rebar=./rebar3 && make
Or use this if you installed Elixir:
  ./autogen.sh && ./configure --with-rebar=mix && make
Start without installing (it recompiles when necessary):
  make relive
It stores config, database and logs in _build/relive/
There's available the well-known script:
  _build/relive/ejabberdctl

Please note this fails immediately:
  r3:do(compile).
This crashes a few seconds later:
  rebar3:run(["compile"]).
Workaround that works correctly:
  ejabberd_admin:update().
