Subject: [PATCH] cmake: set GIT_SHALLOW and UPDATE_DISCONNECTED

* GIT_SHALLOW=TRUE, so we don't pull the full git history,
  as we don't care about it.
* UPDATE_DISCONNECTED=TRUE, to skip the UPDATE step, this change
  somehow works around
  https://gitlab.kitware.com/cmake/cmake/-/issues/19703. otherwise
  cmake keeps building liburing.
