test_lwt_seg6local.sh isn't used by the BPF CI.
Add a new file in the test_progs framework to migrate the tests done by
test_lwt_seg6local.sh. It uses the same network topology and the same BPF
programs located in progs/test_lwt_seg6local.c.
Use the network helpers instead of `nc` to exchange the final packet.
Remove test_lwt_seg6local.sh and its Makefile entry.

Some routes in fb00:: are initialized during setup, even though they
aren't needed by the test as the UDP packets will travel through the
lightweight tunnels.
Remove these unnecessary routes.

After commit afef88e65554 ("selftests/bpf: Store BPF object files with
.bpf.o extension"), we should use *.bpf.o instead of *.o.
In addition, use the BPF_FILE variable to save the BPF object file name,
which can be better identified and modified.

Use temp netns instead of hard code name for testing in case the
netns already exists.

OpenBSD netcat (Debian patchlevel 1.195-2) does not seem to react to
SIGINT for whatever reason, causing prefix.pl to hang after
test_lwt_seg6local.sh exits due to netcat inheriting
test_lwt_seg6local.sh's file descriptors.
Fix by using SIGTERM instead.

The shell file for test_lwt_seg6local contains an early iproute2 syntax
for installing a seg6local End.BPF route. iproute2 support for this
feature has recently been upstreamed, but with an additional keyword
required. This patch updates test_lwt_seg6local.sh to the definitive
iproute2 syntax

test_lwt_seg6local.sh testing script
This test needs root privilege for it's successful execution.
This patch is atleast used to notify the user about the privilege
the script demands for the smooth execution of the test.

Add a new test for the seg6local End.BPF action. The following helpers
are also tested:
- bpf_lwt_push_encap within the LWT BPF IN hook
- bpf_lwt_seg6_action
- bpf_lwt_seg6_adjust_srh
- bpf_lwt_seg6_store_bytes
A chain of End.BPF actions is built. The SRH is injected through a LWT
BPF IN hook before entering this chain. Each End.BPF action validates
the previous one, otherwise the packet is dropped. The test succeeds
if the last node in the chain receives the packet and the UDP datagram
contained can be retrieved from userspace.
