/proc/timer_stats currently reports the user of a timer by pid,
which is a reasonable approach.  However if you are not in
the initial pid namespace the pid that is reported is nonsense.

Therefore until we can make timer_stats pid namespace safe just
disable it in the build if pid namespace support is selected
so we at least know we have a conflict.
