[PATCH 2/2] mergetool: fix running mergetool in sub-directories

[Charles Bailey <charles@xxxxxxxxxxxxx>]

The previous fix to mergetool to use checkout-index instead of cat-file
broke running mergetool anywhere except the root of the repository.

This fixes it by using the correct relative paths for temporary files
and index paths.
