[Buildroot] [git commit branch/2020.05.x] python-scapy: add upstream patch fixing python 2.x compatibility

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=c0d8882e5ec3c07dd439d1e14e749fef9924393d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.05.x

Fixes:
http://autobuild.buildroot.net/results/829/8293529a72ac4c8e93919b8bc0ea758fbb4bc444/

Python 2.x gets confused by rb"string", but not br"string", so add an
upstream patch changing the former to the latter to fix a pycompile issue
with python 2.x:

error:   File "/usr/lib/python2.7/site-packages/scapy/tools/generate_ethertypes.py", line 23
    reg = rb".*ETHERTYPE_([^\s]+)\s.0x([0-9A-Fa-f]+).*\/\*(.*)\*\/"
                                                                  ^
SyntaxError: invalid syntax
