Eric W. Biederman 7b2a69ba70 Revert "vfs: show unreachable paths in getcwd and proc"
Because it caused a chroot ttyname regression in 2.6.36.

As of 2.6.36 ttyname does not work in a chroot.  It has already been
reported that screen breaks, and for me this breaks an automated
distribution testsuite, that I need to preserve the ability to run the
existing binaries on for several more years.  glibc 2.11.3 which has a
fix for this is not an option.

The root cause of this breakage is:

    vfs: show unreachable paths in getcwd and proc

    Prepend "(unreachable)" to path strings if the path is not reachable
    from the current root.

    Two places updated are
     - the return string from getcwd()
     - and symlinks under /proc/$PID.

    Other uses of d_path() are left unchanged (we know that some old
    software crashes if /proc/mounts is changed).

So remove the nice sounding, but ultimately ill advised change to how
/proc/fd symlinks work.
