[PATCH] git-add--interactive.perl: Remove two unused variables

["Thomas \"Enki\" Badie" <thomas.badie@gmail.com>]

The patch 8f0bef6 refactors this script and leaves the `$fh' variable
unused in `diff_applies' and `patch_update_file'.

also want to be sure the way I submit it is the right way. Thanks :)
