Subject: Add hostname to -remsh if none is given

The -name option already computes a default
hostname if none is given. This PR adds the
same behaviour to -remsh. Now we can run:

    erl -name foo -remsh bar
    erl -sname foo -remsh bar

This simplifies deployment scripts as otherwise
they have to compute the hostname by hand or
start an Erlang VM instance only to do so.
