guix-install.sh: Replace `ROOT_HOME` with `~root`

The `ROOT_HOME` variable is natively absent from some systems, however the form
`~root`, which is used by the install functions in this same file, works.

* etc/guix-install.sh (sys_delete_store, sys_delete_guix_daemon)
(sys_delete_user_profiles): Replace `ROOT_HOME` with `~root`.
