Enable `CONFIG_DEBUG_INFO_DWARF5` and `CONFIG_DEBUG_INFO_BTF` in the Linux kernel

Description

The CONFIG_DEBUG_INFO_BTF option is beneficial for certain eBPF programs. It would be ideal if it could be enabled by default in VyOS.

I have personally compiled the kernel and conducted thorough testing, confirming that everything functions flawlessly.

Should debug code really be part of production releases?

Wouldnt it be sufficient that you can enable this on your own if you want a debug build being made?

BTF is required for some eBPF-based programs, e.g. https://github.com/deepfence/ebpfguard/blob/main/docs/gh/prerequisites.md#kernel-capabilities

Although the name of CONFIG_DEBUG_INFO_BTF contains DEBUG, it is not only for debugging.
