toolchain_utils: Reduce CPU freq in nightly tests
The change should provide more stable performance results on ARM devices
by reducing CPU frequency below 95% of max freq.
Experiments show that second from highest frequencies on kevin64 and
scarlet reduce the noice on octane, aquarium and loading.desktop by
20-50%.
BUG=chromium:966514
TEST=95% freq tested on scarlet and kevin64.
