Increase the buffer size of PID

If the length of a PID number crosses 5, printed PID spoils the format
of the trace. In this case, systrace viewer cannot parse this trace.

To prevent this situation, this patch increases the buffer size of
PID from 5 to 8. It will be safe as long as PID is less or equal than
99,999,999.
