[glib: 2/4] dirent: Add trailing nul delimiter to FILENAME_MAX

[Sebastian Dröge <sdroege src gnome org>]

    dirent: Add trailing nul delimiter to FILENAME_MAX
    
    `FILENAME_MAX` is not guaranteed to include a trailing nul delimiter, so
    explicitly add one.
    
    See
    https://www.gnu.org/software/libc/manual/html_node/Limits-for-Files.html:
    `PATH_MAX` is explicitly defined to include a nul delimiter;
    `FILENAME_MAX` is not.
