Existing code calls connect() with a 'struct sockaddr_in6 *' argument
where a 'struct sockaddr *' argument is declared, yielding compile errors
when building for mips64el/musl-libc:
In file included from cgroup_ancestor.c:3:
cgroup_ancestor.c: In function 'send_datagram':
cgroup_ancestor.c:38:38: error: passing argument 2 of 'connect' from incompatible pointer type [-Werror=incompatible-pointer-types]
38 | if (!ASSERT_OK(connect(sock, &addr, sizeof(addr)), "connect")) {

| struct sockaddr_in6 *
./test_progs.h:343:29: note: in definition of macro 'ASSERT_OK'

cc1: all warnings being treated as errors
This only compiles because of a glibc extension allowing declaration of the
argument as a "transparent union" which includes both types above.
Explicitly cast the argument to allow compiling for both musl and glibc.
