cache-calibrator is a single C file that is downloaded as-is, and we
patch it. We also use that file as the license file.
Thus, the file when it is downloaded has a specific hash, but when
saved by legal-info, it has a different hash.
However, we can't store two different hashes for the same _filename_
with different content.
So, we extract the license file as a pre-patch hook, and store it in a
separate file, for which we can now add a hash.
[Peter: add autobuilder reference]
