commit 320e9d6d68b6b347a5bb60ca0eeeab20b9cec9b1
Author: Xianzhu Wang <wangxianzhu@chromium.org>

Mark virtual/modern-media-controls/media/controls/modern/scrubbing.html as Slow

According to the flakiness dashboard, most successful runs of the test
took 5~6 seconds which is borderline of timeout, and sometimes it also
flakily timed out.

Mark virtual/new-remote-playback-pipeline/media/controls/modern/scrubbing.html slow

Other versions of media/controls/modern/scrubbing.html are marked slow,
but not virtual/new-remote-playback-pipeline/, causing this to flakily
time out.
