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.
