[PATCH 1/2] erofs-utils: mkfs: fix double write of long xattr name prefixes

[Jingbo Xu <jefflexu@linux.alibaba.com>]

Fix double write of long xattr name prefixes in non-tarerofs mode.

Besides fix the compiling error of tar.h.  Include "internal.h" to
introduce prototypes of `struct erofs_inode` and `struct erofs_sb_info`.

Fixes: 95d315fd7958 ("erofs-utils: introduce tarerofs")
