Title: Support odbc in erlang R16

I'd rather have erlang-odbc a separate package to be installed along with erlang-base as it is done in Debian, but I lack some nix knowledge how to do that in the same build step.

I also have a branch with this change put in a separate derivation so there is choice whether install it with odbc or without. I can create a pull request for that branch if that's more preferable.
