    data-to-c.py: generate new-line at the end of the file
    
    This is necessary when building glib with icecc. Icecc splits the build
    process into two parts. The file is locally preprocessed with
    -fdirectives-only to resolve any includes. This adds linemarkers to the
    intermediate file. Without the new-line at the end of the file this:
    
     #include "gconstructor_as_data.h"
     #include "glib/glib-private.h"
    
    Is turned into this:
    
    const char gconstructor_code[] = "...";# 1 "glib/glib-private.h"
    ...
    
    The result is a compile error:
    
    In file included from ../glib/gio/glib-compile-resources.c:45:
    gio/gconstructor_as_data.h:1: error: stray '#' in program

ignored due to incorrect nesting
    
    To avoid this, generate gconstructor_as_data.h with a new-line at the end
    of the file.
