Camera2 Legacy: Set a default thumbnail size 

Generally, JPEGs are better with thumbnails, and the default parameters
typically set a basic thumbnail size. In legacy, include a default size in the
templates.

This also works around issues with some devices not producing valid images with no
thumbnail.
