coreutils cksum: Add SHA3/SHAKE support

Add comprehensive tests for SHA3/SHAKE algorithm support

This PR adds comprehensive test coverage for SHA3 and SHAKE algorithms with the --length parameter.

The SHA3/SHAKE implementation was already merged into main. This PR ensures the algorithms are properly tested with various length parameters and edge cases.

Fixes #8933 (test coverage aspect)

Could you please add tests to make sure we don't regress in the future? Thanks
