Disable CL is landing, so lowering priority.

Please note that this test is also failing on reference, but I didn't disable it for ref since apparently we don't do that anymore.

[BotHealth] Disable memory.top_10_mobile_stress on Win/Mac/Linux

Wat? This is a mobile benchmark, shouldn't be running on desktop platforms at all.

Ah, I know what happened. The benchmark was only implicitly disabled on desktop because those platforms "can't launch the DeskClock app"; but we removed that dependency on r446434 with mikecase's work.

I've filed go/catabug/3176 to track the fix of the underlying issue (the decorator should not be needed there in the first place), and sent out https://codereview.chromium.org/2668923002 to do a bit of cleanup on the decorators and bugs they point to.
