examples: nrf24l01_term: reserve RX terminator

Browse source 
read_pkt() terminates the received payload with buff[ret], but a full-size read can leave no room for that trailing NUL byte.

Limit the read length to one byte less than the buffer size so the received payload remains safely terminated before it is printed.
