posixtm: don't reject a time with "60" as the number of seconds
* lib/posixtm.c (posixtime): The code to reject invalid dates would
also reject a time specified with the .60 suffix, whereas POSIX allows
that, in order to accommodate leap seconds. Don't reject that.
(main): Adjust tests accordingly.
* modules/posixtm (Depends-on): Add stpcpy.
