fix missing prototype warning for Qt SELECTSAVED

For whatever reason, Qt relies on late #define of SELECTSAVED
inside files.c.

The prototype in extern.h is therefore not picked up with
as a result of #include "hack.h"

Options were:
1. remove the conditional #if defined(SELECTSAVED) around the
   prototype in extern.h entirely
2. Move the forced #define of SELECTSAVED above the #include "hack.h"
3. Alter the conditional in extern.h to also include the condition for
   the forced #define of SELECTSAVED inside files.c

This goes with option #3.
