selftests/rseq: Fix a building error for riscv arch
RISC-V rseq selftests include asm/fence.h from tools/arch/riscv,
but the rseq Makefile only adds tools/include in the CFLAGS, this
results in the building failure both for native and cross build:
In file included from rseq.h:131,
from rseq.c:37:
rseq-riscv.h:11:10: fatal error: asm/fence.h: No such file or directory
To fix it, add the matching tools/arch/$(ARCH)/include path in the
CFLAGS and derive ARCH from SUBARCH for standalone native builds where
ARCH is not set.
Fixes: c92786e179e0 ("KVM: riscv: selftests: Use the existing RISCV_FENCE macro in `rseq-riscv.h`")
