Wei Wang a870c9b4c9 uid_sys_stats: change to use rt_mutex ...

We see this happens multiple times in heavy workload in systrace
and AMS stuck in uid_lock.

Running process:        Process 953
Running thread: android.ui
State:  Uninterruptible Sleep
Start:

Duration:

On CPU:
Running instead:        system_server
Args:
{kernel callsite when blocked:: "uid_procstat_write+0xb8/0x144"}

Changing to rt_mutex can mitigate the priority inversion
