Refine Redox OS support in native_bootstrap.sh

- Removed unused detect_installed_packages function
- Added git installation check before other packages
- Improved package installation with individual checking
- Made package list more conservative with core essentials only
- Added better error handling that warns instead of failing
- Improved comments and messaging for clarity
- Added note about experimental nature of building on Redox itself

Addresses feedback on issue #1699
