perf tools fixes for v6.4: 2nd batch

- Fix BPF CO-RE naming convention for checking the availability of fields on
  'union perf_mem_data_src' on the running kernel.

- Remove the use of llvm-strip on BPF skel object files, not needed, fixes a
  build breakage when the llvm package, that contains it in most distros, isn't
  installed.

- Fix tools that use both evsel->{bpf_counter_list,bpf_filters}, removing them from a
  union.

- Remove extra "--" from the 'perf ftrace latency' --use-nsec option,
  previously it was working only when using the '-n' alternative.

- Don't stop building when both binutils-devel and a C++ compiler isn't
  available to compile the alternative C++ demangle support code, disable that
  feature instead.

- Sync the linux/in.h and coresight-pmu.h header copies with the kernel sources.

- Fix relative include path to cs-etm.h.
