samples/bpf: Clean up samples/bpf build failes
Remove xdp_samples_user.o rule redefinition which generates Makefile warning and instead override TPROGS_CFLAGS. This seems to work fine when building inside selftests/bpf. That was one big head-scratcher before I found that generic Makefile.target hid this surprising specialization for for xdp_samples_user.o. Main change is to use actual locally installed libbpf headers. Also drop printk macro re-definition (not even used!).
