This airliner was flying at a nice cruising altitude of 10,000m - the man-portable surface-to-air missiles (MANPADS [1]) that the systems you linked to can't easily lock-on to planes that high (only about 6,000m according to the wiki), because they rely on infrared tracking of the plane's engines and exhaust. The defensive systems you listed work by shooting out flares that confuse infrared tracking systems, I believe.
It's more likely that this plane was shot down by a radar-guided system like the BUK [2], at least one of which was captured by Ukrainian separatists recently.
