Subject: runtime: use pipe2 syscall for Pipe in tests

On FreeBSD >= 11 with a kernel built with COMPAT_FREEBSD11 but not
COMPAT_FREEBSD10, the pipe syscall is not available. Thus, tests using
runtime.pipe fail with ENOSYS. As suggested by Ian, fix this by calling
pipe2(0) in these tests and fall back to pipe() in case of ENOSYS.

Fixes #42659
