remsim: fix TPDU response size transmission 

the TDPU response data size can be up to 256.
this length cannot be stored in a uint8_t, which would cause the
length to become 0, no data being send, and the reader reset the
card because of misbehaviour of the card (i.e. no/malformed
response leading to the timeout of the waiting time).
