refactor: change return value of TermFindFiles

It turns out that `TermFindFiles` and  `TermFindOne` were made
to return hard links just for testfind. Nowhere else in the code is 
hard links count used.
Testfind will later directly get the count from its own fileset without 
the need for calling `TermFindFiles`
