Tests: do not add transitive dependencies in multi-module tests

Prefer to have all module dependencies, including dependencies on
stdlib/reflect, declared explicitly. This allows to have tests on
situations like the one in KT-45308: three modules A<-B<-C, where C
doesn't depend on A, which was compiling correctly with the old JVM
backend before 1.5, but started to fail with JVM IR in 1.5.

Also simplify the code a bit, remove duplicated logic.
