Improve kadmin parsing of time intervals

When parsing time intervals in kadmin commands, try
krb5_string_to_deltat() first, then fall back to subtracting the
current time from get_date().  If we do fall back, treat "never" as a
zero interval, and error out rather than yield a huge interval if
get_date() returns a time in the past.

Notable behavior differences: bare numbers of seconds and suffixed
numbers (e.g. "5m" or "6h") are now supported for all intervals;
HH:MM:SS and HH:MM are now treated as intervals rather than absolute
times with the current time subtracted.
