Allow dumpsys to read total DMA-BUF heap pool size
These permissions are added to allow dumpsys to read
/sys/kernel/dma_heap/total_pools_kb.
Fixes the following sepolicy denials:
avc: denied { read } for name="total_pools_kb" dev="sysfs" ino=3252
scontext=u:r:system_server:s0 tcontext=u:object_r:sysfs:s0 tclass=file permissive=1
avc: denied { open } for path="/sys/kernel/dma_heap/total_pools_kb"
dev="sysfs" ino=3252 scontext=u:r:system_server:s0 tcontext=u:object_r:sysfs:s0
tclass=file permissive=1
avc: denied { getattr } for path="/sys/kernel/dma_heap/total_pools_kb"
dev="sysfs" ino=3252 scontext=u:r:system_server:s0 tcontext=u:object_r:sysfs:s0
tclass=file permissive=1
