Fix two more minor Gnus typos
* lisp/gnus/mail-source.el (mail-source-delete-old-incoming): The old code had two minor bugs: first, it multiplied by 1/65536 instead of by 1/86400. Second, it called current-time twice and glued part of the two results together, resulting in a race. Fix both bugs by simplifying the code and using time-to-number-of-days.
