    testing: nettest: Fix TCP server terminator bounds
    
    The TCP nettest server receives up to TEST_BUFFER_SIZE bytes and then 
appends a NUL terminator before checking for the exit command. A full-size 
receive can therefore write one byte past the receive buffer.
    
    Reserve one extra byte for the terminator while keeping the recv() limit 
and echo length capped at TEST_BUFFER_SIZE.
