system_health.memory_desktop failing on multiple builders

Builders failed on: 
- Linux Perf: 
  https://build.chromium.org/p/chromium.perf/builders/Linux%20Perf

Seems to consistently be browse:media:tumblr that's failing, and has been for as far back as the flakiness dashboard can see. Going to go ahead and disable but not kick off a bisect because there's no revision range this far after the initial failure.

The relevant log seems to suggest that we're having problems finding the "#tumblr_lightbox_center_image" element.
