packaging: setup: do not update RedirectServletReportsPage

It is not the engine's job to update this, but rather Reports'.
Currently if setting up both of them at same engine-setup run, there is
a race condition. A first solution was http://gerrit.ovirt.org/29640 ,
which works when both on same host but fails if separate.
