diff: factor out src/dst prefix setup

We directly manipulate diffopt's a_prefix and b_prefix to set up either
the default "a/foo" prefix or the "--no-prefix" variant. Although this
is only a few lines, it's worth pulling these into their own functions.
That lets us avoid one repetition already in this patch, but will also
give us a cleaner interface for callers which want to tweak this
setting.
