"^C" problem when multithreads stop at "sudo -v"

when multithreads stop at "sudo -v", you need input ^C more than
one time to terminate depanneur. The reason is main thread blocked
by "lock($DETACHING)" and it can't response to ^C immediately. So
use another lock variable "$SUDOV_LOCK" for "sudo -v".
