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".
