Do not fetch Kotlin stubs for versioned files from multi-release jars (KT-26439)

An incomplete list of inner class files might be stored in versioned
directory and that ruins Kotlin stub building.

Another reason for excluding such files, that they are duplicated
in different declarations lists such as `Navigate -> Class...` action.
