bpftrace: fix buildpaths QA issues

* Avoid line statements from bison to fix:

* there are still few more buildpaths issues with ptest enabled:

* lower buildpaths from ERROR_QA to WARN_QA when ptest is enabled
  fixing .cmake files might be simple, but the embedded path to dwarf_data.h
  in bpftrace_test will be more complicated, so will leave it to
  someone actually using bpftrace (and its ptest).
