Check that kotlin.stdlib is explicitly required in module-info

Writing a Jigsaw-modular Kotlin program which doesn't require
kotlin.stdlib doesn't make sense because it most likely will fail at
runtime, on access to anything from the standard library. Previously, we
checked that kotlin.stdlib was in the module graph, but that's not
enough, we should also check that the source module requires it.
'-Xallow-kotlin-package' can be used to disable the error.

Add a test checking that an indirect (transitive) dependency is also OK
