This patch expands test coverage for EPERM tests to include connect and
bind calls and rounds out the coverage for sendmsg by adding tests for
sendmsg_unix.

Without this fix, the bind4 and bind6 programs will reject bind attempts
on big endian systems. This patch ensures that CI tests pass for the
s390x architecture.

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:

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