unix: use dup3 in Dup2 on all Linux platforms

The minimum required Linux kernel version for Go 1.18 will be changed to
2.6.32, see golang/go#45964. The dup3 syscall was added in 2.6.27, so it
can be used instead of the dup2 syscall which is not implemented on
arm64 and riscv64 or blocked on android.

For golang/go#45964
