ci: metrics: Be more aggressive in our KSM settings

Rather than rely on the distro default KSM settings and
trying to wait 'long enough' to ensure our tests have
settled down, let's be more active about setting up
KSM.
And along with that, let's start to use the auto KSM
mode of the memory density tests to match.
