t3004: add test for ls-files on symlinks via absolute paths

When symlinks in the working tree are manipulated using the absolute
path, git dereferences them, and tries to manipulate the link target
instead.

This causes most high-level functions to misbehave when acting on
symlinks given via absolute paths. For example

  $ git add /dir/repo/symlink

attempts to add the target of the symlink rather than the symlink
itself, which is usually not what the user intends to do.

This is a regression introduced by 18e051a:
  setup: translate symlinks in filename when using absolute paths
(which did not take symlinks inside the work tree into consideration).

Add a known-breakage test using the ls-files function, checking both if
the symlink leads to a target in the same directory, and a target in the
above directory.
