Subject: [for-next][PATCH 17/25] tools/rv: Stop gracefully also on SIGTERM

From: Gabriele Monaco <gmonaco@...hat.com>

Currently the userspace RV tool starts a monitor and waits for the user
to press Ctrl-C (SIGINT) to terminate and stop the monitor.
This doesn't account for a scenario where a user starts RV in background
and simply kills it (SIGTERM unless the user specifies differently).
E.g.:
 # rv mon wip &
 # kill %

Would terminate RV without stopping the monitor and next RV executions
won't start correctly.

Register the signal handler used for SIGINT also to SIGTERM.
