core/legal-info: use hash file from version sub-dir

When we have multiple versions for a package, and the licensing terms
depend on the version actually selected (e.g. like Qt5), storing the
hashes for those license files in the .hash file is broken: the infra
will ensure that all hashes for a file do match, which would not be the
case here.

We fix that by first looking for a hash file in the version sub-dir
first, and if that does not exist, then we use the main hash file.

Drop the useless intermediate variable 'ret'.

Update the documentation accordingly.
