cksum: stops when one of given files doesn't exist

[D9nni]

GNU cksum shows an error message when a file does not exist and continues work with the next given arguments, while uutils cksum stops when error occurs.
GNU:

$ cksum README.md nothing Cargo.toml 
4037539306 8038 README.md
cksum: nothing: No such file or directory
3830277208 20970 Cargo.toml

uutils:

$ coreutils cksum README.md nothing Cargo.toml 
4037539306 8038 README.md
cksum: nothing: No such file or directory

I could take this issue on, should be a quick fix to just match on the attempt to open the file and then carry on.
