restore the former installation path for 2.5.x-y).

Note that freetype isn't to blame here – including the freetype headers
in the way that was removed from freetype 2.5.1 has been deprecated for
a long time.

From the freetype CHANGES file:
 CHANGES BETWEEN 2.5 and 2.5.1
 [...]
  II. IMPORTANT CHANGES
  [...]
    - The header  file layout  has been changed.   After installation,
      all files are now located in `<prefix>/include/freetype2'.

      Applications  that  use   (a)  `freetype-config'  or  FreeType's
      `pkg-config' file to get the include directory for the compiler,
      and (b) the documented way for header inclusion like

        #include <ft2build.h>
        #include FT_FREETYPE_H
        ...

      don't need any change to the source code.

The projects that are broken now should rather fix their code to
correctly include the freetype headers using

 #include <ft2build.h>
 #include FT_FREETYPE_H
