hammer: Enable CONFIG_SHA256_UNROLLED in RO region
Makes RW verification a little faster (268ms vs 294ms), at no
cost since RO still has enough space. Doesn't make any difference
in time to active USB, as USB enumeration is still the bottleneck.
BRANCH=none
BUG=b:35647963
TEST=Boot hammer, check that [0.267707 RW verify OK] is better
than without this patch ([0.294128 RW verify OK]).
