    KCM: Set kdc_offset to zero initially
    
    Resolves: https://pagure.io/SSSD/sssd/issue/4100
    
    KCM assumed that the client library would always set the KDC offset, but
    that's not always the case, especially when using multiple krb contexts
    from the client application:

    Heimdal also creates ccaches with zero kdc_offset:
        https://github.com/heimdal/heimdal/commit/9f58896af958ae5e6e3ebde8c48dad4eda841986
    so we should do the same..
