chuck 4063facb4a Fix output of linprocfs stat entry
The Linux /proc/stat entry has grown over time

 v2.5.41 <
   user, nice, system, idle
 v2.5.41
   user, nice, system, idle, iowait, irq
 v2.6.11
   user, nice, system, idle, iowait, irq, softirq, steal
 v2.6.24
   user, nice, system, idle, iowait, irq, softirq, steal, guest
 v2.6.32 >
   user, nice, system, idle, iowait, irq, softirq, steal, guest, guest_nice

Some applications (e.g. nodejs) depend on the correct number of entries
and will abort otherwise.

Fix is to print the correct number of entries based on the value of
osrelease set either in sysctl or the jail settings. Change is similar
to approach used by illumos.
