ipatests: wait for SSSD to become online in backup/restore tests
The backup/restore tests are calling 'id admin' after restore
to make sure that the user name can be resolved after a restore.
The test should wait for SSSD backend to become online before
doing any check, otherwise there is a risk that the call to
'id admin' fails.
