Fixes usage of WallpaperManager to make it optional.

As the main javadoc states:
"An app can check whether wallpapers are supported for the current user,
by calling {@link #isWallpaperSupported()}, and whether setting of
wallpapers is allowed, by calling {@link #isSetWallpaperAllowed()}."

Test: manual verification on automotive
