[PATCH] erofs-utils: lib: fix packed xattr prefix seek

erofs_xattr_flush_name_prefixes() records the current packed file
offset, writes xattr prefixes with erofs_io_pwrite(), and then seeks
back to the new absolute end position.

Use SEEK_SET for that final lseek(). SEEK_CUR adds the tracked offset
to the unchanged file position and can leave the packed file offset too
far forward.
