Check that added entropy is at least somewhat acceptable.
BRANCH=none
BUG=b:38486828
TEST=make BOARD=hammer -j tests
./util/flash_ec --board=hammer --image=build/hammer/test-entropy.bin
EC console: runtest, get around 4000/1000 (=4) bits of entropy, value
matches (roughly) the value obtained using the awk script.
TEST=make run-entropy
