    Make krb5_cc_new_unique create DIR: directories
    
    When we use krb5_cc_new_unique to create a new cache in a directory
    cache collection, we will fail if the directory doesn't exist yet.
    
    Go ahead and preemptively create it, as we do during krb5_cc_resolve,
    before attempting to create a new file under it.
