Use clang for libpcap and CGO compilation

[brb]

For the BPF code compilation we already use clang. Let's use the same compiler for the libpcap.a and CGO compilations.

@brb hi I want to work on this issue can you guide me through it

[brb]

@swastik959 Hi, thanks for taking it. A C compiler is used in the following places:

• https://github.com/cilium/pwru/blob/main/Makefile#L19
• https://github.com/cilium/pwru/blob/main/Makefile#L25

The issue is about using Clang for those in https://github.com/cilium/pwru/tree/main/.github/workflows.

@brb do I only need to change the CC and LIBPCAP_CC to clang

[brb]

Most likely yes - in the GH workflows.
