[RFC PATCH 1/9] tools/rv: Do not skip idle in trace

[Gabriele Monaco <gmonaco@redhat.com>]

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).
The current condition for per-task monitors (config_has_id) does not
check that config_my_pid isn't 0 to skip. In case we pass -s, we show
events triggered by RV but don't show those triggered by idle (PID 0).

Fix the condition to account this scenario.
