Both the bpf and bpf-next tree have suitable BPF selftest configurations available for usage with the latest kernel now upstream. While we do test on 4.9 and 5.5 kernels as well, there we just download prebuilt binaries. The configuration we use for building selftests is always the upstream one. With this change we remove the checked-in configuration, as it is now no longer needed. Signed-off-by: Daniel Müller <deso@posteo.net>
