self: Ensure the daemon refers to the right 'guix' command.
Previously it would refer to /var/guix/profiles/per-user/root/current-guix/bin/guix, which would fail when that profile does not exist. This is notably the case when using 'channel-instance->package' as done in commit 7e6d8d366a61f951936ed83371877ce006f679f6. * gnu/packages/package-management.scm (guix-daemon)[arguments]: In 'install phase, honor environment variable 'GUIX'. * guix/self.scm (whole-package)[wrap]: New procedure. Use it.
