Subject: [PATCH] selftests/net: fix section name when using xdp_dummy.o

Since commit 8fffa0e3451a ("selftests/bpf: Normalize XDP section names in
selftests") the xdp_dummy.o's section name has changed to xdp. But some
tests are still using "section xdp_dummy", which make the tests failed.
Fix them by updating to the new section name.
