Trying to run dumpsys from the serial console generates the
following errors:

  shell@device:/ # dumpsys power
  [ 3244.099015] binder: 2259:2259 transaction failed 29201, size 28-8
  [ 3244.099291] type=1400 audit(1403313679.642:12): avc: denied { read write } for pid=2259 comm="dumpsys" path="/dev/console" dev="tmpfs" ino=6188 scontext=u:r:system_server:s0 tcontext=u:object_r:console_device:s0 tclass=chr_file permissive=0
  Error dumping service info: (Unknown error -2147483646) power

and the operation fails. Allow binderservicedomains to perform
writes to /dev/console.
