Subject : base: Set initial thread priority in ThreadFunc.
Author  : reveman
Commit description:
  
Instead of relying on base::InitOnThread to set the initial thread
priority to normal, always set it to thread_params->priority in
ThreadFunc.

The result is that thread priority will be set correctly on all
posix platforms and not only Android.
