Move the `REQUIRES_FULL_LIBC` dependency from `config LORA` to
`config LORAWAN`. The commit that added the `select` (f590d4fa) mentions
that this is required by `loramac-node`, which is only used by LoRaWAN,
not the base LoRa code.
This results in small FLASH savings when compiling the samples, but can
result in larger savings in more complex applications:
