This reverts commit f1b333f (Use Ioctl{SetPointerInt,GetInt} from
golang.org/x/sys/unix on linux), changing the code to what it was after
commit dbd69c5. This fixes a blocker bug on s390.

The original description from commit dbd69c5 follows:

    On big-endian architectures unix.IoctlGetInt() leads to a wrong result
    because a 32 bit value is stored into a 64 bit buffer. When dereferencing
    the result is left shifted by 32. Without this patch ptsname() returns
    a wrong path from the second pty onwards.
    To protect syscalls against re-arranging by the GC the conversion from
    unsafe.Pointer to uintptr must occur in the Syscall expression itself.
    See the documentation of the unsafe package for details.
