Description: Agent installation fails due to zeek-af_packet-plugin not being able to find the correct kernel headers during compilation. This happens when running in a container (VM in my case under QubesOS), where the incorrect kernel may be returned by uname -r.

Error:

Could NOT find KernelHeaders (missing: KERNELHEADERS_ROOT_DIR)

Need a way to specify kernel path for ./configure and maybe option to compile using zeek-af_packet-plugin master branch (not sure if current release is compatible with Zeek 4.0?).

Expected Result: zeek-af_packet-plugin compiles correctly, allowing agent installation to complete without errors.

Steps to Reproduce:

1. Install the dynamite python package in a container or VM.
2. Attempt to install the agent on the same instance using sudo dynamite agent install --inspect-interfaces eth0 --targets https://dynamite-monitor:9200
3. All steps succeed, except the compilation of zeek-af_packet-plugin

This is related to:

• Zeek 4.0.0 zkg install zeek/zeek-af_packet-plugin#24
• Detect when running in a container in FindKernelHeaders.cmake zeek/zeek-af_packet-plugin#29
• Allow optional arguments for build_command zeek/package-manager#98.

Btw, I was able to successfully manually compile the plugin from git source using these changes. However, the agent install command does not pickup that it is installed on the system and still tried to compile it from source itself, which errors. Is there any good workaround for this issue?
