Fix stub loading for crossinline lambdas compiled by older Kotlinc (EA-105730)

Older kotlinc versions (1.1.5?) didn't generate the 'INNERCLASS' attribute for some anonymous classes, e.g. for 'crossinline' lambdas.
An example: 'Timer().schedule(1000) { foo () }'

Normally, stub loader checks if the class is 'ClassFileViewProvider.isInnerClass()', and ignores the class file.
Without the 'INNERCLASS' attribute this check fails. As the stub loaded isn't created to deal with anonymous classes nicely, it fails miserably.
This commit explicitly ignores classes with local visibility.
