download_hash.py: support for 'multi-hash' file + runc 

runc upstream does not provide one hash file per assets in their
releases, but one file with all the hashes.
To handle this (and/or any arbitrary format from upstreams), add a
dictionary mapping the name of the download to a lambda function which
transform the file provided by upstream into a dictionary of hashes,
keyed by architecture.
