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().
