common : fix split model migration (#21019)
Sadly the manifest does not list all required files, i honestly thought
it was the case

Without the files listed we don't have the sha256, so if the first file
is valid, and all others have the correct size, then we can assume we
are good and do the migration...

Here my test:

    $ find /home/angt/.cache/llama.cpp
