SceUtilitySavedataFileListEntry correction

SceUtilitySavedataFileListEntry should be 80 bytes long.
It worked on x86 platforms due to struct padding (sizeof(SceUtilitySavedataFileListEntry) was 80 bytes), but corrupt memory on iOS (where sizeof(SceUtilitySavedataFileListEntry) was correct 76 bytes).

Fixes "Savedata is corrupted" loading error on iOS with some games (Valkyria Chronicles 2 and 3).
