installer: Take 'guix system init' exit code into account.
This allows the installer to distinguish success from failure, and also ensures the shell that runs 'guix system init' exits upon completion. * gnu/installer/utils.scm (run-shell-command)[pause]: New procedure. Add "exec" before COMMAND in the script. Guard 'invoke' call and handle 'invoke-error?'. Add call to 'pause' on completion. * gnu/installer/final.scm (install-system): Remove 'false-if-exception'.
