Fix battery level code in adafruit_ble.cpp (#6648)

* Fix battery level code in adafruit_ble.cpp

The code in tsk_core/protocol/lufa/adafluit_ble.cpp that polls the
battery level for the Adafruit feather BLE controller reads the
regulated voltage, not the raw voltage coming from the battery. To do
that, the Adafruit Feather docs say you should read from pin A9:
https://learn.adafruit.com/adafruit-feather-32u4-basic-proto/power-management#measuring-battery-4-9.
(See also
https://learn.adafruit.com/adafruit-feather-32u4-bluefruit-le/pinouts#logic-pins-2-9.)

I'm not sure why, but analogRead(9); doesn't read the correct pin.
Checking all available analog pins experimentally, it turns out that
analogRead(7); returns the correct value. So the code above should read:

    state.vbat = analogRead(7);

* Update tmk_core/protocol/lufa/adafruit_ble.cpp
