[build] Fix MinGW errors while building dlg with FreeType on Windows.

* builds/freetype.mk (DLG_DIR): New variable to include dlg's header
files.
(INCLUDES): Added `DLG_DIR'
When using MinGW to build dlg along with FreeType on Windows there are
missing dlg's include files errors. Therefore we need to add path to dlg's
include files to remove the errors.

* src/base/ftsystem.c: Fix `-Wformat' warnings.
