systemd: record the timestamps as early as possible
The time for systemd initialization and selinux policy loading is accounted to the initrd or the kernel, which is wrong. Instead of: Startup finished in 5.559s (firmware) + 36ms (loader) + 665ms (kernel) + 975ms (initrd) + 1.410s (userspace) = 8.647s the more correct output is: Startup finished in 5.559s (firmware) + 36ms (loader) + 665ms (kernel) + 475ms (initrd) + 1.910s (userspace) = 8.647s
