samples/bpf: build with -D__TARGET_ARCH_$(SRCARCH)

While $ARCH can be relatively flexible (see Makefile and tools/scripts/Makefile.arch), $SRCARCH always corresponds to a directory name under arch/. Therefore, build samples with -D__TARGET_ARCH_$(SRCARCH), since that matches the expectations of bpf_helpers.h.
