cargo-update-recipe-crates: generate checksum for each crates

Browse Source 
This is related to checksum verification introduction from
https://patchwork.yoctoproject.org/project/bitbake/patch/20230315131513.50635-1-frederic.martinsons@gmail.com/

I also choose to raise an exception if:
 - no crates can be found
 - no Cargo.lock file exist

Otherwise the generated inc file will silently be emptied.

(From OE-Core rev: c75b924a3de02625aa90ad4db4403f00d1ffeba2)
