Do not wait till close to expirey

Add the `-a` option.

Quoting the man page:

> When run with either the -K flag or a command, always renew tickets
each time krenew wakes up.  Without this option, krenew will only try to
renew a ticket as often as necessary to prevent the ticket from
expiring.  With this option, krenew will renew tickets according to the
interval specified with the -K flag.

> This behavior probably should have been the default behavior of -K.  The
default was not changed to avoid changes for existing users, but for
new applications, consider always using -a with -K.
