t/cindex: fix test when worktree PWD is a symlink

Our code aims to respect $ENV{PWD} (and therefore symlinks) as
much as possible to ensure portability across devices when repos
and indices are on portable or shared storage.  Thus we can't
rely on Cwd::abs_path and ought to favor File::Spec->rel2abs
whenever absolute paths are required.

I noticed this when working on a VM where my worktree is a
symlink to a more reliable device.
