Revert backward incompatible change that removes default object attributes
    
    The tpm2-tools 3.1.0 release contains a backward incompatible change that
    was introduced by commit e103bbf5117 ("objectattrs: clear before or'ing
    in values"), that changed the way that object attributes were specified.
    
    Before there were a set of default attributes and the user could specify
    additional attributes to be used, but after the mentioned commit the user
    must specify all attributes.
    
    This is a user visible change that changes the tools semantics, so is not
    a suitable change for a MINOR version number increment, according to the
    Semantic Versioning document (https://semver.org) since it breaks rule 2:
    
    2.MINOR version when you add functionality in a backwards-compatible manner
