selftests/bpf: remove bpf_util.h from BPF C progs Though currently there is no problem including bpf_util.h in kernel space BPF C programs, in next patch in this stack, I will reuse libbpf_num_possible_cpus() in bpf_util.h thus include libbpf.h in it, which will cause BPF C programs compile error. Therefore I will first remove bpf_util.h from all test BPF programs. This can also make it clear that bpf_util.h is a user-space utility while bpf_helpers.h is a kernel space utility.

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.
