Revert of On W3C test import, always skip large files that may fail to upload.

Revert of On W3C test import, always skip large files that may fail to upload. (patchset #1 id:1 of https://codereview.chromium.org/2628913003/ )

Reason for revert:
I believe that this didn't actually solve the problem properly - 
In the latest import, some tests are failing because they depend on files that are too large that were already checked in (in media/*), and after this change, the files are removed but the tests are still imported, causing this failure: https://build.chromium.org/p/chromium.infra.cron/builders/w3c-test-autoroller/builds/7870/steps/update%20wpt/logs/stdio
