    bitbake: bitbake-diffsigs: drop naive logic for removing duplicate files
    
    This logic doesn't work in practice, certainly not with current versions
    where sigdata files are preserved in the stamps directory and therefore
    there will often be multiple sigdata files - you can now easily get
    files for the same signature from sstate and the stamps directory with the
    result that bitbake-diffsigs reports nothing has changed. Instead, let's
    change the find_siginfo function in OE-Core to simply not return
    duplicates so we don't have to filter them out here.
