build_packages: add option to automatically switch cpu governors

The powersave governor can take quite a while to get up to speed
when building things, so add a tip for users to automatically set
it to performance during the life of the build.

BUG=chromium:1008932
TEST=`./build_packages --noautosetgov` issues powersave warning
TEST=`./build_packages --autosetgov` switches to performance & then back to powersave
