selftests/bpf: Workaround for older vm_sockets.h.

Some distros ship with older vm_sockets.h that doesn't have VMADDR_CID_LOCAL
which causes selftests build to fail:
/tmp/work/bpf/bpf/tools/testing/selftests/bpf/prog_tests/sockmap_listen.c:261:18: error: ‘VMADDR_CID_LOCAL’ undeclared (first use in this function); did you mean ‘VMADDR_CID_HOST’?
    261 |  addr->svm_cid = VMADDR_CID_LOCAL;
        |                  ^~~~~~~~~~~~~~~~
        |                  VMADDR_CID_HOST

Workaround this issue by defining it on demand.
