Allow lists for md5 check

Allows lists when checking md5. See https://github.com/michael-k/youtube-dl/commit/1a1ab231b71f8bae5d0b6ff14d12022401590786 for an example.

This prevents creating multiple commits for hash sums that switch back and forth. (See https://github.com/rg3/youtube-dl/commit/1e60e5546e437197bd9a0eabe7e8d23c5470a4db)
