Disable test to verifying BLE offloaded scan batching

The test is trying to provide means to assess whether
a device can support BLE (Bluetooth Low Energy) batched
scanning when the device reports the capability through
BluetoothAdapater#isOffloadedScanBatchingSupported().

However, it is not easy to validate this in a scalable way.
Hence the test is disabled for now.
