Fix the vmstat -i output on ARM.

Browse Source 
The consumers of hw.intrnames expect a NULL byte at end of the string
containing the interrupt names.

On ARM all the interrupt name slots are initialized and this leave no room
for the terminating NULL byte, which makes vmstat read beyond the end of
intrnames.
