Fix skiko.js unpacking for k/js target (#5105)

K/JS and K/Wasm have differences in the packaging logic, and therefore
we need to account for it when unpacking Skiko files.

Fixes [CMP-5649](https://youtrack.jetbrains.com/issue/CMP-5649)


## Testing
- Added a test, which checks the state of k/js distribution


This should be tested by QA
