Remove call to update_resources.py for WebRTC

This script is about to be removed in favor of using
download_from_google_storage.py in depot tools for
the download instead (based on .sha1 files).

When https://codereview.chromium.org/60513012/ is
landed and the builders are updated to actually execute
the hooks (https://codereview.chromium.org/59793009)
the resource files will be downloaded using that instead.
Even if executing the hooks means a bit of extra execution
time for the build, this approach is simpler and means
less maintenance.
