From: He Zhe <zhe.he@windriver.com>

To make the native python3 always used,

- Use sed one-liner instead
- Add substitution for ${S}/scripts/bpf_helpers_doc.py to fix the
  following warning.

File "/usr/lib/python3.6/sysconfig.py", line 421, in _init_posix
_temp = __import__(name, globals(), locals(), ['build_time_vars'], 0)
ModuleNotFoundError: No module named '_sysconfigdata'

This issue is first reported by Joel Stanley <joel@jms.id.au>
The sed one-liner is credited to Anuj Mittal <anuj.mittal@intel.com>
