diff: generate pretty filenames in prep_temp_blob()
Naturally, prep_temp_blob() did not care about filenames. As a result, GIT_EXTERNAL_DIFF and textconv generated filenames such as ".diff_XXXXXX". This modifies prep_temp_blob() to generate user-friendly filenames when creating temporary files. Diffing "name.ext" now generates "XXXXXX_name.ext".
