tools/rv: Do not skip idle in trace
Currently, the userspace RV tool skips trace events triggered by the RV
tool itself, this can be changed by passing the parameter -s, which sets
the variable config_my_pid to 0 (instead of the tool's PID).
This has the side effect of skipping events generated by idle (PID 0).
Set config_my_pid to -1 (an invalid pid) to avoid skipping idle.
