test defs: function 'is_newest' now works also with directories

Reported by Jim Meyering against automake master (see bug#9147) and
by Adam Sampson against automake 1.11.3 (see bug#10730).

* tests/defs (is_newest): Call 'find' with the '-prune' option,
so that it won't descend in the directories (which could cause
spurious results).
* THANKS: Update.

Backported from commit v1.11-914-gb6a40fa (originally on master).
