    lib/oe/sstatesig: fix wildcard matching wrong task signature files
    
    With a '*' as a wildcard for the signature here we can also match a
    portion of the task name with the result that we may match a sigdata
    file for the wrong task. Luckily the signature is always the same
    length - 32 characters - so we can simply use 32 '?' characters instead.
    (A regex would have been another alternative, but the wildcard should be
    effective and I felt like a regex would complicate the code more than
    this solution).
    
    Fixes [YOCTO #11763].
