Add a version of update engine that does not send stats

update_engine_nostats has the same functionality as the update_engine
but without interaction with statsd libraires and without build
dependency on it.

Test: Apply an upadte to an aosp cf vm - note that merge stats are
      reported in logcat.
      Replace update engine with the nostats service in the product
      packages and apply an update - note that stats reporting is
      skipped.
