Subject: [PATCH bpf-next 2/2] selftests: bpf: Add missing per-arch include path

From: Björn Töpel <bjorn@...osinc.com>

The prog_tests programs do not include the per-arch tools include
path, e.g. tools/arch/riscv/include. Some architectures depend those
files to build properly.

Include tools/arch/$(SUBARCH)/include in the selftests bpf build.

Fixes: 6d74d178fe6e ("tools: Add riscv barrier implementation")
