fix: leave out core files the core refuses by size

A core extra resolved by name shipped on existence platforms even when
the core's own size check turns the copy away. The RetroPie pack carried
the 128 KB Apple IIGS ROM as Basilisk II's ROM (min 512 KB). The builder,
the manifest and verify now read validation.core_size_refusal, which
accepts a copy any version of the same profile slot takes.
