generic mode, checking that it fails correctly.

bpf_offload caught a spurious warning in TC recently, but the error
message did not provide enough information to know what the problem
is:
FAIL: Found 'netdevsim' in command output, leaky extack?
Add the extack to the output:
FAIL: Unexpected command output, leaky extack? ('netdevsim', 'Warning: Filter with specified priority/protocol not found.')

net/lib/py/nsim.py already contains the most useful parts
of the netdevsim wrapper classes. Reuse them.

Non-ancient ip (iproute2-5.15.0, libbpf 0.7.0) refuses to load
the sample with maps because we don't generate BTF:
libbpf: BTF is required, but is missing or corrupted.
ERROR: opening BPF object file failed
Enable BTF by adding -g to clang flags. With that done
neither of the programs load:
libbpf: prog 'func': error relocating .BTF.ext function info: -22
libbpf: prog 'func': failed to relocate calls: -22
libbpf: failed to load object 'ksft-net-drv/net/sample_ret0.bpf.o'
Andrii explains that this is because we don't specify
section names for the code. Add the section names, too.

Maps are removed asynchronously. Either there's a bigger delay
now or the test has always been flaky. Retry waiting in the loop.

We're building more python tests on the netdev side, and some
of the classes from the venerable BPF offload tests can be reused.
