sepolicy : remove property context for vendor.qcom.bluetooth

On PRODUCT_COMPATIBLE_PROPERTY_OVERRIDE enable we are seeing BT
is not compliance so removing this.
vendor.qcom.bluetooth:
As this property is only been set once and read (not dynamic) we
are removing the context which will make this property to be as
vendor_default_prop which will enable  vendor process  to read.
