feat(deploy): install slice + sysctl artifacts and apply via sysctl --system

Browse source 
Copies l4d2-game.slice and l4d2-build.slice into
/usr/local/lib/systemd/system/, installs 99-left4me.conf into
/etc/sysctl.d/, and runs sysctl --system so the perf baseline is
live this deploy, not on next reboot.
