When building bpf selftests on arm64, the following error will occur:
progs/loop2.c:20:7: error: incomplete definition of type 'struct user_pt_regs'
Some archs, like arm64 and riscv, use userspace pt_regs in bpf_tracing.h, which causes build failure when bpf prog use macro in bpf_tracing.h. So let's use vmlinux.h directly.
