python3-grpcio: fix native build failure on ubuntu 16.04 and centos 8

Browse Source 
1. Keep '-std=c++11' and '-std=gnu99' to fix native build error
with old gcc (such as gcc 5.4.0 on ubuntu 16.04); for clang, remove
them through setting GRPC_PYTHON_CFLAGS at do_compile in bb recipe

2. While export CC="gcc ", cc_args is empty, it will
cause subprocess.Popen always return 1. On centos 8, if you don't
install package libatomic, there will be a native build error
`cannot find /usr/lib64/libatomic.so.1.2.0'.

Add no harm '-g' to cc_args if cc_args is empty.
