Fix save tga when IL_ORIGIN_UPPER_LEFT is set

[Mizzrym1]

Remove flip two times:
if (TempImage->Origin == IL_ORIGIN_UPPER_LEFT)
Temp |= 0x20; //set 5th bit

Fix this:
ilInit();

ILuint imageID;
ilGenImages(1, &imageID);
ilBindImage(imageID);
ilEnable(IL_ORIGIN_SET);
ilOriginFunc(IL_ORIGIN_UPPER_LEFT);

if(!ilLoad(IL_TYPE_UNKNOWN, "in.tga"))
	std::cerr << "ilLoad Error" << std::endl;

ilEnable(IL_FILE_OVERWRITE);
if(!ilSave(IL_TGA, (const ILstring) "out.tga"))
	std::cerr << "ilSave Error" << std::endl;

ilDeleteImages(1, &imageID);
ilShutDown();

in.tga:

out.tga:
