ABI inference for unsupported targets fails for modules that don't produce production artifacts

[fzhinkin]

kotlinx-datetime's serialization module is a test-only module and it does not produce "production" artifacts. Yet, an attempt to dump ABI for kotlinx-datetime on linux will fail on the serialization module with:

The target iosArm64 is not supported by the host compiler and there are no targets similar to iosArm64 to infer a dump from it.

BCV should not try inferring the ABI for modules w/o sources.
