Fix BOARD_SYSTEMSDK_VERSIONS checks
BOARD_SYSTEMSDK_VERSIONS must be greater than or equal to the minimum
of PRODUCT_SHIPPING_API_LEVEL and BOARD_API_LEVEL. If BOARD_API_LEVEL
is not defined, read BOARD_SHIPPING_API_LEVEL. If both board api
levels are not defined, compare only with PRODUCT_SHIPPING_API_LEVEL.
