3e689141e6 selftests: Use consistent include paths for libbpf 
Fix all selftests to include libbpf header files with the bpf/ prefix, to
be consistent with external users of the library. Also ensure that all
includes of exported libbpf header files (those that are exported on 'make
install' of the library) use bracketed includes instead of quoted.

To not break the build, keep the old include path until everything has been
changed to the new one; a subsequent patch will remove that.

1cb59a6074 selftests/bpf: fix perf_buffer on s390 
perf_buffer test fails for exactly the same reason test_attach_probe
used to fail: different nanosleep syscall kprobe name.

Reuse the test_attach_probe fix.
