    Fix kadmin addprinc -randkey -kvno
    
    Commit f07bca9fc94a5cf2e3c0f58226c7973a4b86b7a9 made addprinc -randkey
    use a single RPC request, but the server-side handling always creates
    the random keys with kvno 1.  If a kvno is specified in the RPC
    request, set the kvno of the key data after creating it.  Reported by
    Andreas Ladanyi.
