Subject: [PATCH] fetch_disk_trailer: Don't truncate the size verif
Reference:https://github.com/gdraheim/zziplib/commit/2a84ae73e93b0c1f4f12f2c58104f8327d10e41b
* We must check if the tail obtained have the size of the zzip_disk_trailer
struct. end - tail should be at least >= of the size but not size - 2.
Where truncated by 2 was good for pre-C99 compilers.
* Fix gdraheim#165
