rtla/osnoise: Add an option to set the threshold
Add the -T/--threshold option to set the minimum threshold to be considered a noise to osnoise top and hist commands. Also update the man pages.

Stop the trace if the total sample is higher than the argument in microseconds.
If **-T** is set, it will also save the trace to the output.

+**-T**, **--threshold** *us*
+
+ Specify the minimum delta between two time reads to be considered noise.
+ The default threshold is *5 us*.
