Use the full buffer when computing md5/sha256 sums
No wonder these were slower than expected. We were only reading 4
(32-bit) or 8 (64-bit) bytes at a time and feeding it to the hash
functions. Define a buffer size constant and use it correctly so we feed
8K at a time into the hashing algorithm.
This cut one larger `-Sw --noconfirm` operation, with nothing to
actually download so only timing integrity, from 3.3s to 1.7s.
This has been broken since the original commit eba521913d6 introducing
OpenSSL usage for crypto hash functions. Boy do I feel stupid.
