timer/debug: Change /proc/timer_stats from 0644 to 0600 ...
The timer_stats facility should filter and translate PIDs if opened
from a non-initial PID namespace, to avoid leaking information about
the wider system. It should also not show kernel virtual addresses.
Unfortunately it has now been removed upstream (as redundant)
instead of being fixed.
For stable, fix the leak by restricting access to root only. A
similar change was already made for the /proc/timer_list file.
