reltool: Add load_dot_erlang rel option
This adds a rel tuple to the reltool release specific configuration format as {rel, Name, Vsn, RelApps, Opts} to support the use of {rel, Name, Vsn, RelApps, [{load_dot_erlang, false}]} for preventing the insertion of {apply,{c,erlangrc,[]}} into the release script file and the release boot file. This change makes it possible to prevent releases generated with reltool from attempting to load a ${HOME}/.erlang file which is desirable for production deployment of Erlang, to have greater control of what BEAM evaluates. The ${HOME}/.erlang file lacks visibility and its location on the filesystem separate from where the release lives means it can be misused in a way that lacks visibility.
