Subject: [PATCH] v2v: Move calculation of overlay directory to common code.

There is a tiny functional change in this patch, since overlay_dir is
now always evaluated once (eg. even in --inplace mode), whereas
previously it was evaluated twice but only in copying mode.

(cherry picked from commit a7fb3d601ab2ae3cdf2074d4c47afe59f00eea6d)
