JVM IR: fix generation of equals/hashCode for fun interfaces over references

... in case `-Xno-optimized-callable-references` is enabled. Before this
change, the generated abstract equals/hashCode methods were considered
as accidental overrides because they did not have equals/hashCode from
the supertype in the overriddenSymbols list.
