This is not a problem with the media attribute matching logic, and therefore, not really CSS related. Removing the label.

Fix preloadScanner double download issue with link preload and media

The preloadScanner was not checking the media attribute when preloading
<link rel=preload> based resources, due to a bug that bypassed that logic for preloads.

This CL fixes that and adds unit tests to make sure it stays fixed.

Low end check should be <= 512MB, not just <

The current check misses devices with exactly 512MB.
