Fix potential AbstractMethodError on KotlinJvmBinaryClass.getContainingLibrary()

Compiler supposed to generate such method inside the
LocalFileKotlinClass class, but because of the KT-18489 method
getContainingLibrary is not generated. Because of that we potentially
could get AbstractMethodError. In order to fix that we are adding
explicit ovverride in java super class
