fix: Complete Zero-OS initramfs networking and script permissions

- Add net_failover and failover modules for virtio_net dependency resolution
- Copy modules from both drivers/net and net/ kernel directories
- Fixes 'Unknown symbol net_failover_destroy/create' errors when loading virtio_net
- Set execute permissions on all zinit init scripts (*.sh files)
- Include proper kernel module metadata files (modules.order, modules.builtin, modules.builtin.modinfo)
- Expanded module search to include failover-related networking modules
- Now includes 77 network driver modules with complete dependency chain
- Ensures depmod -a works correctly without warnings
- Complete VirtIO network stack functionality with proper script execution
