[Detail]
BT vendor lib cannot read the valid BD address from nvram
since selinux violation.
Android P version changes nvdata path to /mnt/vendor/nvdata.
If want to open fstab when using nvram function, it needs
search policy.
[Solution]
allow mtk_hal_bluetooth mnt_vendor_file:dir search

Feature: BT AOSP
[Detail]
AOSP has defined neverallow rules
to restrict direct access to system files.
[Solution]
Since MTK does not use "/data/misc/bluedroid/" to
store BT address. It should be alright to remove
this kind of thing.
