Checksums are currently not being checked upon download. This commit
corrects them with the intent for us to turn on checking soon.
Not sure what reason causes the checksum incorrect. I am aware someone
complain on github that checksum of some tarballs are changed without
any updating. We also can't guarantee developers always fill correct
checksum. Once we turn on checksum upon download, we can catch in up in
time.
Test Plan:
