Adding /proc/timer_list to the masked paths list
Adding /proc/timer_list to the masked paths list

/proc/timer_list seems to leak information about the host. Here is
an example from a busybox container running on docker+kubernetes.

 # cat /proc/timer_list | grep -i -e kube
 <ffff8800b8cc3db0>, hrtimer_wakeup, S:01, futex_wait_queue_me, kubelet/2497
 <ffff880129ac3db0>, hrtimer_wakeup, S:01, futex_wait_queue_me, kube-proxy/3478
 <ffff8800b1b77db0>, hrtimer_wakeup, S:01, futex_wait_queue_me, kube-proxy/3470
 <ffff8800bb6abdb0>, hrtimer_wakeup, S:01, futex_wait_queue_me, kubelet/2499
