Do not explicitly use --force-compositing-mode in memory/throughput tests; use the default config for that platform instead.

Explicitly using --force-compositing-mode enabled FCM on bots where it is blacklisted in http://crrev.com/221643 as we decided to make the flags take precedence over the blacklist decision.

This depends on https://codereview.chromium.org/23447045/ as it would otherwise disable FCM on perf bots for Mac 10.8.
