Here is a concise summary of the pull request changes:

Summary: This pull request updates the tools installation script to include bpf2go (v0.15.0) from Cilium's ebpf repository. Key changes include:

• Introduction of a new install_bpf2go function to handle installation using go install.
• Bypassing the go_install function for bpf2go installation.
• Setting the GOBIN environment variable to the vendor directory for installation.

Impact: This update enhances the project's tools by adding bpf2go support, which may improve eBPF-related development workflows. The new install_bpf2go function provides a dedicated installation mechanism, ensuring a consistent and reliable installation process.

Observations/Suggestions:

• It would be beneficial to include a brief explanation in the commit message or documentation about the motivation behind adding bpf2go and its expected benefits for the project.
• Consider adding tests or validation to ensure the install_bpf2go function works correctly and bpf2go is properly installed.
• Review the GOBIN environment variable setting to ensure it doesn't conflict with other dependencies or installations in the project.
