There is a potential for us to hit a type conflict when including
netinet/tcp.h with sys/socket.h, we can remove these as they are not
actually needed.
Fixes errors like the below when compiling with gcc BPF backend:

Augment the current set of options that are accessible via
bpf_{g,s}etsockopt to also support SO_REUSEPORT.

I'm planning to extend it in the next patches. It's much easier to
work with C than BPF assembly.
