backend/bitbox02: update dev mcu and ble firmwares

Compiled from
BitBoxSwiss/bitbox02-firmware@2544f08.

BLE fw binary also taken from there.

We only update the multi firmware as all our testing devies are
multis. We upgrade ignoring errors as it is unsigned (we prepend the
v9.22 sigs just to have the right format).
