fpsensor: Implement command to read positive_match_secret.
Add EC command to read positive_match_secret on match success.
If the attempt to read is 5 seconds after the match, the read is not
allowed (the readable bit for positive match secret is cleared).
Test that the command can read the data correctly and can
read for each finger only once. Test that attempt to read secret
after deadline will be rejected.
BRANCH=nocturne
BUG=chromium:927095
TEST=make buildall
TEST=tested enrollment, matching and multifinger on DUT nocturne
TEST=tested that if biod requests to download template and secret
for a finger that's not currently matched, reading secret will fail.
