Revert "xz: Use pipe2() if available."
This reverts commit 7a11c4a8e5e15f13d5fa59233b3172e65428efdd. It is a problem when libc has pipe2() but the kernel is too old to have pipe2() and thus pipe2() fails. In xz it's pointless to have a fallback for non-functioning pipe2(); it's better to avoid pipe2() completely. Thanks to Michael Fox for the bug report.
