README.org: Add info about vterm in NixOS

Browse Source 
I hit a problem with `epkgs.vterm` from `nixos-20.09` being too old and thus missing `vterm-goto-char` which is present in newer versions of `epkgs.vterm`.

I added a note to clear this up for future users, and added two other changes/clarifications as well:

* Changed `epkgs.emacs-libvterm` -> `epkgs.vterm`, as the old name is deprecated.
* Added note that `epkgs.vterm` already contains a `vterm-module.so`
* Added note that the version of `emacs` needs to be recent enough and that otherwise bugs might occur.

This already contains a version of =vterm-module.so=, so NixOS users need
not compile the module themselves as described below.
Note: The =nixpkgs=-version that is used needs to be compatible with the rest
of the plugins installed in =doom=. Therefore it might be necessary to pull in
=emacs= and/or =emacsPackagesNgGen= from =unstable= or another channel. Otherwise
arbitrary functionality of =vterm= might not work.
** Compilation tools for vterm-module.so
When you first load vterm, it will compile =vterm-module.so= for you. For this
