checkpolicy: remove extraneous policy build noise

Reduce noise when calling the checkpolicy command line. In Android, this
creates unnecessary build noise which we'd like to avoid.

  Rule of Silence
  Developers should design programs so that they do not print
  unnecessary output. This rule aims to allow other programs
  and developers to pick out the information they need from a
  program's output without having to parse verbosity.

An alternative approach would be to add a -s (silent) option to these
tools, or to have the Android build system redirect stdout to /dev/null.
