This is indeed a bit how it is, though there are very little champions build pure tank.

Alistar and Leona, for example, are tagged as tank, but are build support-tank. Amumu is also tagged as tank, but some people buy some ability power on him, because of his godlike AP ratios (1.0 on huge AoE, such stuff). Malphite can be build pure tank, but you can also take some attack damage or ability power on him, plus he is very efficient at shutting down top laners like Riven or Renekton, who have only physical damage.

I wouldn't say that you should put pure tanks in the jungle, but that you should put pure cc machines like Nautilus in the jungle. Because, as you said, they mostly scale of coodlowns. There are also tanks, like Galio, that are better put elsewhere (Galio in mid, for example), because they don't have that much cc, but do have nice ratios, or are just an excellent counter (like Galio is for any AP mid. He builds defense and gets damage this way).

In general, you just put in the jungle what you can use best there. Sometimes you need a good ganker, and take Nautilus or Shaco, sometimes you need a counterjungler, and you take Shyvana, and so on.
