ectool/trng: Add "rand" host command for testing RNG
This host command and corresponding ectool command allows us to generate
random numbers with the MCU's RNG and process the resulting output with
tools to validate the statistical randomness, such as dieharder
(https://webhome.phy.duke.edu/~rgb/General/dieharder.php) and NIST SP
800-22
(https://csrc.nist.gov/publications/detail/sp/800-22/rev-1a/final).
