tc-policy: Fix issue of too many TC-BPF filter prog attached multi
...
This seems to be a common occuring issue with tc cmdline.
And the C-code have inherited the issue in the API.
Trying to replace a TC-BPF prog often result in appending a new prog
(as a new tc filter instance).
Be careful to set both handle and prio and the replace flag.

tc-policy: Use bpftool skeleton header generate feature
...
The reason for going this route is that this allow us to
create a user binary that contains the BPF object file.
Thus, we can avoid having to load the BPF file from
a specific location or having to be in same dir as file.
