    Fix kvno argument order in t_authdata.py
    
    In t_authdata.py, correct a kvno invocation so that it doesn't rely on
    GNU getopt behavior.
    
    In k5test.py, add POSIXLY_CORRECT=1 to the test environment to prevent
    future mistakes in this category.
    
    [[email protected]: added test environment setting; edited commit
