Tobias Klauser a98ae47d97 unix: on ARM GNU/Linux let Pipe fall back to pipe ...

Follow CL 165217 which did this for package syscall.

Android O seems to require Pipe to call the pipe2 system call.
But kernel version 2.6.23 only supports pipe, not pipe2.
So try pipe2 first, then fall back to pipe.

Updates golang/go#30549
