Hob: Add filter for images listed in image combo

Define BBUI_IMAGE_WHITE_PATTERN variable to indicate which image is
allowed to be displayed in image combobox.

Define BBUI_IMAGE_BLACK_PATTERN variable to indicate which image is NOT
allowed to be displayed in image combobox.

This fixes [YOCTO #1581]
