OldPackageNameDep: check for dependency using pkgmoved name

[arthurzam]

Results on current master. Important to note that some of them block on it's own previous name (like net-analyzer/snmpclitools). Not sure if this is fine or should be whitelisted.

Resolves: #659

Let's include self-blockers as it's either based on a misunderstanding of pkgmoves, might indicate a missing one, or a workaround for an old issue which can be removed eventually (e.g. botched pkgmove).

Lovely and elegant!
