[bug#53063] [PATCH wip-harden-installer 09/14] installer: Use the command capturing facility for guix init.

[Josselin Poiret]

* gnu/installer/newt/final.scm (run-install-shell): Remove procedure,
as run-command-in-installer now takes care of everything.
(run-final-page): Directly use install-system.
* gnu/installer/final.scm (install-system): Restore PATH inside the
container, and use run-command-in-installer.
