Exclude the configurations of source sets from dependency resolution

The `*Api`, `*Implementation`, `*CompileOnly`, and `*RuntimeOnly`
configurations of a `KotlinSourceSet` must not be resolved directly, as
they lack attributes needed to choose a Kotlin MPP variant, and they
must not be candidates in variant-aware resolution of a project
dependency either.

With Gradle 5.3, these configurations failed to resolve anyway, as they
had no proper `org.gradle.usage` attribute, and the disambiguation
rules of the 'java-base' plugin conflicted with the Kotlin rules.
