nixos/bash: Improve Emacs detection for PS1

Browse source 
That's one of my itches - when I'm sshing from Emacs' term to a NixOS
machine, it doesn't detect that I'm running emacs and showing a title
escape sequence. This commit fixes it, checking against $TERM to
prevent this from ever bothering anyone again.
