selftests/bpf: Add tests for cgroup unix socket address hooks
These selftests are written in prog_tests style instead of adding
them to the existing test_sock_addr tests. Migrating the existing
sock addr tests to prog_tests style is left for future work. This
commit adds support for testing bind() sockaddr hooks, even though
there's no unix socket sockaddr hook for bind(). We leave this code
intact for when the INET and INET6 tests are migrated in the future
which do support intercepting bind().
