Fix UID tracking in ProcessCpuTracker.

Many processes are incorrectly listed under UID 0 (e.g. surfaceflinger)
because some "/proc/$PID/stat" files are with user "root".
The user of the folder "/proc/$PID/" is the correct one to use.

Bug: 119218763
Test: adb shell dumpsys batterystats -c | grep surfaceflinger
