powerhint: Add WriteOnly flag for PA_KILL to avoid SELinux error

Browse source 
The node "/sys/kernel/vendor_mm/pa_kill/reclaim_kb" is write-only. So we need to add WriteOnly flag to prevent powerhal to read the node.

SELinux errors:
avc:  denied  { dac_read_search } for  comm="android.hardwar" capability=2  scontext=u:r:hal_power_default:s0 tcontext=u:r:hal_power_default:s0 tclass=capability permissive=0
avc:  denied  { dac_override } for  comm="android.hardwar" capability=1  scontext=u:r:hal_power_default:s0 tcontext=u:r:hal_power_default:s0 tclass=capability permissive=0

Bug: 350830411
Change-Id: I649e263a5371782184ce712fef3e8d42941806d7
Test: adb shell dumpsys android.hardware.power.IPower/default, check if any avc denied messages
Flag: EXEMPT config json change
