FreeBSD has quite unfortunate behaviour when dealing with keywords that
are missing in one of the manifests being compared -- namely, they
ignore these instances.
Commit 21723a3974 ("*: fix comparison of missing keywords") re-added
this behaviour after the introduction of the Compare API, but
unfortunately it was implemented in the Compare API itself -- meaning
that library users (which didn't want this behaviour) were silently
opted into it.
This patch moves the behaviour to the command-line, where it belongs
(a future patch in this series will allow users to opt-out of this
unfortunate behaviour, as well as some other unfortunate FreeBSD
compatibility behaviours).
