universal7885: Allow vendor_init to set powerhal init prop

Browse source 
The Pixel libperfmgr has following code :
std::thread initThread([&]() {
        ::android::base::WaitForProperty(kPowerHalInitProp.data(), 1);
        hm->Start();
        dlpw->Init();
    });

which is basically
declare thread {
        if (powerhalprop_is_not_set) wait;
        else (powerhal_prop_is_set) init_other_threads;
}.start();

But in logcat
<11>[   21.988418]  [2:           init: 2815] init: Unable to set property 'vendor.powerhal.init' from uid:0 gid:0 pid:2816: SELinux permission check failed
<36>[   21.989189]  [3:    logd.auditd: 3586] type=1107 audit(1654915533.291:146): uid=0 auid=4294967295 ses=4294967295 subj=u:r:init:s0 msg='avc: denied { set } for property=vendor.powerhal.init pid=2816 uid=0 gid=0 scontext=u:r:vendor_init:s0 tcontext=u:object_r:vendor_powerhal_prop:s0 tclass=property_service permissive=0'

So the powerhal's thread was not being run. This commit fixes seplicy to allow vendor init to set the powerhal init prop. May fix some issues on DT2W and deep sleep
