xdp-tools: upgrade to upstream 1.5.4

rebase xdp-tools from upstream xdp-tools 1.5.4. there is
Makefile conflict when rebase because 1.5.4 added xdp-forward.
manually resolve the rebase conflict by put loongfire xdp program
at the end:

for example instruction from deepseek:

Open the Makefile in a text editor and locate the conflict:

makefile
ifneq ($(BPFTOOL),)
<<<<<<< HEAD
UTILS += xdp-bench xdp-forward xdp-monitor xdp-trafficgen
=======
UTILS += xdp-bench xdp-monitor xdp-trafficgen xdp-synproxy
>>>>>>> d8ebb16 (Add xdp-synproxy)
endif

Understand the conflict:

The HEAD (upstream/main) version includes xdp-forward.

Your commit (d8ebb16) adds xdp-synproxy but removes xdp-forward.

Resolve the conflict by including both changes:

Keep xdp-forward from HEAD.

Add xdp-synproxy from your commit.

The merged line should look like this:

makefile
UTILS += xdp-bench xdp-forward xdp-monitor xdp-trafficgen xdp-synproxy
Remove the conflict markers (<<<<<<<, =======, >>>>>>>).

edit result:

ifneq ($(BPFTOOL),)
UTILS += xdp-bench xdp-forward xdp-monitor xdp-trafficgen xdp-synproxy
endif

Save the file after making these changes.

Stage the resolved Makefile and continue the rebase:

git add Makefile
git rebase --continue

repeat editing Makefile and git rebase --continue for below program

xdp-dnsrrl
