Lower the priority of the threads in logd/logcat.

(cherry pick from commit 98b580b4857f81fc32e9e84954704ee0278029b1)

sched_batch implies only a penalty to latency in scheduling, but
does not imply that the process will be given less cpu time. Increase
the nice level to 10 to prioritize it below ui threads.
