systemd: Don't start without essential system services

Starting bees right after local-fs.target is probably not what we want,
as basic setup of the system might not have been done (like udev,
cryptsetup, sysctl, swap, etc).

Let's start only after sysinit.target instead which guarantees that all
basic setup has been done, most importantly, sysctl, udev, and swap have
been setup which may apply important tweaks, configuration, and tuning.
