    Fix bugs in kdcpolicy commit
    
    Commit d0969f6a8170344031ef58fd2a161190f1edfb96 added tests using
    "klist ccachname -e", which does not work with a POSIX-conformant
    getopt() implementation such as the one in Solaris.  Fix
    t_kdcpolicy.py to use "klist -e ccachename" instead.
    
    The tests could fail if the clock second rolled over between kinit and
    kvno.  Divide service ticket maximum lifetimes by 2 in the test module
    to correctly exercise TGS policy restrictions and ensure that service
    tickets are not constrained by the TGT end time.
    
    Also use the correct trace macro when a kdcpolicy module declines to
    initialize (my mistake when revising the commit, noted by rharwood).
    
    ticket: 8606
