Subject: NetBSD/OpenBSD: Compile fix and proper detection of pipe2

Add the necessary defines for HAVE_PIPE2 for NetBSD and OpenBSD depending
on OS version when pipe2(2) was added. This also fixes the compile error
on NetBSD if -Werror=unused-function for ignore_sigpipe() as the
HAVE_PIPE2 tree is prior to O_NOSIGPIPE in create_pipe().
