shell: Create cached profile directory once connected to the daemon.

Fixes a regression introduced in d12c4452a49b355369636de1dfc766b5bad6437b,
where ‘guix shell’, on a fresh installation, would attempt to create the
cached profile directory under /var/guix/profiles/per-user/$USER, which only
guix-daemon can do, on the user’s first connection.

* guix/scripts/shell.scm (options-with-caching): Remove ‘mkdir-p’ call for
ROOT’s parent directory.  Add ‘create-gc-root-directory?’ key to the result.
* guix/scripts/environment.scm (guix-environment*): Honor
‘create-gc-root-directory?’ key.
