Subject: [PATCH] refactor: Make eBPF build optional in packet-gateway build
 script

- Change eBPF build from required to optional with graceful fallback
- Add match statement to handle build success, failure, and missing cargo-build-bpf cases
- Add cargo warnings when eBPF build fails or cargo-build-bpf is not installed
- Remove panic on build failure to allow compilation without eBPF toolchain
