Tobias Klauser 9d34fc5108 runtime: remove fallback to pipe on platforms with pipe2
On Linux, the minimum required kernel version for Go 1.18 was be changed
to 2.6.32, see #45964. The pipe2 syscall was added in 2.6.27.

All other platforms already provide the pipe2 syscall in the minimum
supported version:
- DragonFly BSD added it in version 4.2, see
  https://www.dragonflybsd.org/release42/
- FreeBSD added it in version 10.0, see
  https://www.freebsd.org/cgi/man.cgi?pipe(2)#end
- NetBSD added it in version 6.0, see
  https://man.netbsd.org/pipe2.2#HISTORY
- OpenBSD added it in version 5.7, see
  https://man.openbsd.org/pipe.2#HISTORY
- Illumos supports it since 2013, see
  https://www.illumos.org/issues/3714
- Solaris supports it since 11.4

This also allows to remove setNonblock which was only used in the pipe
fallback path on these platforms.
