Update dosfstools

* Version 3.0.28
* Update filenames in source
* Remove unnecessary symlink to fsck
* Commit "Recode short filenames from DOS codepage (default 437)." has
  been reverted since we do not have access to iconv
* Commits cherry-picked on top of 3.0.28:
    - mkfs.fat: fix incorrect int type
    - Prevent out of bound array read in date_dos2unix()
