 emacs 26 tries loading original user's .emacs after su to root

Indeed, as a first-approximation, it uses "~$LOGNAME/.emacs" but "$HOME/.emacs.d/elpa/".

In many circumstances "~$LOGNAME/" is the same as "$HOME/", and in yet
other circumstances Emacs uses "$HOME/.emacs" (which I find very handy)
rather than "~$LOGNAME/.emacs".

I'd rather we drop this special case of using "~$LOGNAME/.emacs" when we
decide that we're in "su".  I know it's long standing behavior, but
there are many other ways for the user to get the same result, so
I think we can get rid of this dangerous quirk.
