add--interactive: remove unused diff colors

When color support was added, we colored the diffs ourselves.
However, 4af756f3 changed this to simply run "git diff-files"
twice, keeping the colored output separately.

This makes the internal diff color variables obsolete with
one exception: when splitting hunks, we have to manually
recreate the fragment for each part of the split. Thus we
keep $fraginfo_color around to do that correctly.
