Arnaldo Carvalho de Melo 1fd450f992 libbpf: Fix up generation of bpf_helper_defs.h
$ make -C tools/perf build-test

does, ends up with these two problems:

  make[3]: *** No rule to make target '/tmp/tmp.zq13cHILGB/perf-5.3.0/include/uapi/linux/bpf.h', needed by 'bpf_helper_defs.h'.  Stop.
  make[3]: *** Waiting for unfinished jobs....
  make[2]: *** [Makefile.perf:757: /tmp/tmp.zq13cHILGB/perf-5.3.0/tools/lib/bpf/libbpf.a] Error 2
  make[2]: *** Waiting for unfinished jobs....

Because $(srcdir) points to the /tmp/tmp.zq13cHILGB/perf-5.3.0 directory
and we need '/tools/ after that variable, and after fixing this then we
get to another problem:

  /bin/sh: /home/acme/git/perf/tools/scripts/bpf_helpers_doc.py: No such file or directory
  make[3]: *** [Makefile:184: bpf_helper_defs.h] Error 127
  make[3]: *** Deleting file 'bpf_helper_defs.h'
    LD       /tmp/build/perf/libapi-in.o
  make[2]: *** [Makefile.perf:778: /tmp/build/perf/libbpf.a] Error 2
  make[2]: *** Waiting for unfinished jobs....

Because this requires something outside the tools/ directories that gets
collected into perf's detached tarballs, to fix it just add it to
tools/perf/MANIFEST, which this patch does, now it works for that case
and also for all these other cases.

Fixes: e01a75c159 ("libbpf: Move bpf_{helpers, helper_defs, endian, tracing}.h into libbpf")
