SELinux policy for reading system ion heap size
The policy is only for userdebug or eng builds to verify usefulness of
ion heap size measuring in practice.
The size of the system ion heap is read by the system server similarly
to other memory measurements.
Example /sys/kernel/debug/ion/heaps/system (repeated lines removed):
client pid size

orphaned allocations (info is from last known client):

total orphaned 0
total 55193600
deferred free 0
----------------------------------------------------
0 order 4 highmem pages in uncached pool = 0 total
0 order 4 lowmem pages in uncached pool = 0 total
1251 order 4 lowmem pages in cached pool = 81985536 total
VMID 8: 0 order 4 highmem pages in secure pool = 0 total
Test: m -j
Test: Pulling statsd metric returns non-zero value
