[OE-core][PATCH] classes/reproducible_build: Skip SDE for non-finalizing virtual recipes

["Joshua Watt" <JPEWhacker@gmail.com>]

Don't capture the source date epoch for recipes that are not being
finalized. This prevents a virtual recipe (e.g. multilib) from
attempting to read the source date epoch file from the non-virtual
recipes workdir.
