Tolerate "--dismiss-keyguard"

In UDC the flag was renamed to "--dismiss-keyguard" in a
change that has been reverted. Before and after, the
correct flag is "--dismiss-keyguard-if-insecure".

However, since UDC CTS passes in this flag, and must
pass against QPRs too, we need to accept this renamed
flag for at least the next year.
