Exported debug build uses release GDNative library about wwise-godot-integration

[alessandrofama]

More information:
Godot exports both libraries when exporting. It just happens that one library gets overwritten as both debug and release libs share the same name.

Adding the release gdnlib to the export filters fixes this, but is not very user friendly:

Trying to skip the gdnlib in the build export script does not fix the issue:

	var use_debug = false;

	func _export_begin(features, debug, path, flags):
		var lib_path:String = ProjectSettings.get_setting("autoload/Wwise")
		if lib_path == "*res://wwise/bin/wwise-gdnative-debug.gdns":
			use_debug = true
		if "iOS" in features:		
			# Add missing StoreKit framework for iOS
			add_ios_framework("StoreKit.framework")
			
	func _export_file(path, type, features):
		if use_debug:
			if path == "res://wwise/bin/wwise-gdnative-release.gdnlib":
				skip()
			if path == "res://wwise/bin/wwise-gdnative-release.gdns":
				skip()

Trying to skip the release .dll or .dylib there does not work as _export_file only seems to iterate through resource files.

One solution could involve renaming the libraries to WwiseGDNative-Debug and -Release.
