erlang: fix problem with ODBC on 10.9

Even with installed unixODBC on Mavericks Erlang R16B02 continues to use the library iODBC:

1> odbc:start().
ok
2> odbc:connect("",[]).
{error,"[iODBC][Driver Manager]No data source or driver specified, dialog prohibited SQLSTATE IS: IM007 Connection to database failed."}

Closes Homebrew/homebrew#24283.
