Fix Symbol not found: (_JSGlobalContextSetInspectable) (facebook#44185)

Summary:
Pull Request resolved: facebook#44185

This change will fix a symbol not found for JSC Runtime.

The `if` check was not a compile time check, therefore the symbol ended up in the binary even if it is not available.

Following this post on [Apple forum](https://forums.developer.apple.com/forums/thread/749534), this changes should do the trick.
