ipa-restore: restart services at the end

When IPA was not installed on the restore target host, and
when httpd was already running, "ipactl stop" does not stop
httpd. "ipactl start" at the end of the restore tool will
therefore not restart httpd either.
Calling "ipactl restart" at the end of the restore fixes the
issue, and as an added bonus, makes sure IPA can restart itself
properly.
