Fix macOS app bundle path - find .app directory dynamically

The previous fix used the wrong path for macOS app bundles. It was missing
the .app directory name in the path construction.

Problem:
- Was looking for: <outputPath>/Contents/Resources/sitl
- Actual location: <outputPath>/<AppName>.app/Contents/Resources/sitl

Fix:
- Dynamically find the .app bundle in outputPath
- Construct correct path with .app directory included

This should now properly remove non-native SITL binaries from macOS builds.
