Tri Vo d276b4349d Remove access to 'sysfs' files from healtd and charger.
We rely on vendors to label all dependencies of healthd/charger under
/sys/class/power_supply with sysfs_batteryinfo type.

Bug: 65643247
Bug: 32659667
Test: boots without denials from healthd, to sysfs_batteryinfo or to
sysfs_msm_subsys.
Test: charging with device turned off works without /sys denials.
