ipa[server,replica,client]: Fix moved sysrestore and is_ipa_configured

https://pagure.io/freeipa/issue/8458 moved more things to the ipalib and
ipalib.facts:

- sysrestore has been moved from ipalib.install to ipalib
- is_ipa_configured has been moved from ipaserver.install.installutils to
  ipalib.facts

Fixes: #394 (TASK [ipaclient : Install - IPA client test] Error: module
                  'ipalib.install.sysrestore' has no attribute
                  'SYSRESTORE_STATEFILE')
