libbpf: Fix syscall access arguments on riscv
[ Upstream commit 8a412c5c1cd6cc6c55e8b9b84fbb789fc395fe78 ]
Since commit 08d0ce30e0e4 ("riscv: Implement syscall wrappers"), riscv
selects ARCH_HAS_SYSCALL_WRAPPER so let's use the generic implementation
of PT_REGS_SYSCALL_REGS().
Fixes: 08d0ce30e0e4 ("riscv: Implement syscall wrappers")
