core: Execute first boot presets in an enable-only preset-mode.
This means any existing enabled units well be preserved and no
pre-created symlinks will be removed. This is done on first boot, when
the assumption is that /etc is not populated at all (no machine-id
setup). For minimal containers that gives a significant first boot
speed up, approximately ~20ms / ~16% in my trials.
