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.
