skin_engine/backdrops: Have to reload default backdrops from setting when it changed.

When skins use the default backdrop (via %X(-) or no %X at all) and the setting
changes it needs to be reloaded, otherwise when changing themes the new theme
could show the backdrop from the previous theme. The same needs to be
done when re-selecting the same theme after USB because the backdrop file was
potentially overwritten.

Fixes FS#12892 and FS#12942.
