unix: implement Pipe using pipe2 syscall on all linux platforms
Most architectures currently already implement Pipe using the pipe2
syscall. Only 386, amd64, mips{,le}, ppc and sparc64 still use the pipe
syscall. However, some systems (e.g. Android seccomp policies) block
that syscall, see golang/go#40828 for an example.
The pipe2 syscall was added in Linux kernel version 2.6.27. The minimum
required Linux kernel version for Go 1.18 will be changed to 2.6.32
per golang/go#45964 so it is possible to unify the implementation of
Pipe using the pipe2 syscall.
Same as CL 350530 did for package syscall.
For golang/go#45964
Fixes golang/go#40828
