find_*: Fix search order when the environment duplicates some HINTS

Refactoring in the topic merged by commit v3.2.0-rc1~400 (Merge topic
'refactor-search-path-construction', 2014-11-13) introduced a bug that
filters out duplicate paths in an incorrect order.  Restore the search
path to its documented order even when duplicate paths are present.
