[Bug 1813883] Re: reuseport_bpf in net from kernel_selftests failed to build on X-4.15

Found on Xenial 4.15 as well. So this is something we might need to fix
in the generic kernel.

** Summary changed:

- reuseport_bpf in net from kernel_selftests failed to build on AWS X-4.15
+ reuseport_bpf in net from kernel_selftests failed to build on X-4.15

** Package changed: linux-aws (Ubuntu) => linux (Ubuntu)
