presets: "disable" all passive targets by default

Officially we default to a "enable *", even though pretty much everybody
overrides this with "disable *". We have a bunch of targets and services which
should not be enabled by default. In case the default policy is not overriden,
our passive units would be enabled by presets, which is generally not useful at
all. So let's explicitly mark them as disabled.

Note that this effectively changes very little. E.g. on Fedora, all the units
listed in this patch were "disabled" already.

Fixes #14648.
