Backup: jo_backup_save_file() new args

[slinga-homebrew]

I need to be able to set the language for saves. Japanese saves have Japanese comments. Without setting the save language to Japanese they do not render correctly in the BIOS.

I will push a better implementation

jo_backup bkp;

jo_backup_init_file(&bkp);
bkp.fname = "TEST.BKP";

... jo_backup_save(&bkp);

[johannes-fetz]

You can set language using jo-engine abstraction or native and same for the save date

I deleted jo_backup_save_file_contents_on_partition(). Use jo_backup_save() instead
