samples: canbus: isotp: increase stack size and make it configurable

Browse source 
Increase the stack size of the two RX threads used in the ISO-TP sample
from 512 to 1024 bytes as the former is too small for some CAN
controller/SoC combinations.

Make both the RX thread stack size and priority configurable via Kconfig.
