[PATCH tip/core/rcu 02/28] torture: Don't kill gdb sessions

The rcutorture scripting will do a "kill -9" on any guest OS that exceeds
its --duration by more than a few minutes, which is very valuable when
bugs result in hangs. However, this is a problem when the "hang" was due
to a --gdb debugging session.

This commit therefore refrains from killing the guest OS when a debugging
session is in progress. This means that the user must manually kill the
kvm.sh process group if a hang really does occur.
