[ Upstream commit 98af3746026c3eccb51b43181c41e001fe73f7af ]
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.
