emacs: Adjust 'guix environment' popup.

* emacs/guix-command.el (guix-command-improve-environment-argument): Use
  "E" for '--expose' and "S" for '--share' to distinguish them from
  '--expression' and '--system' accordingly.  Make '--ad-hoc' an option
  taking packages instead of a simple switch.
  (guix-command-rest-argument): Complete shell command instead of
  packages for '--' argument.
  (guix-command-additional-arguments): Add fake 'packages' argument.
  New variable.
  (guix-command-additional-arguments): Use it.
  (guix-command-post-process-environment-packages,
  guix-command-post-process-environment-ad-hoc): New functions.
  (guix-command-post-processors): Add "environment" command with the new
  argument processors.
