As suggested in the comments on https://android-review.googlesource.com/#/c/141560/ drop BOARD_SEPOLICY_UNION and simplify the build_policy logic. Union all files found under BOARD_SEPOLICY_DIRS. Unlike BOARD_SEPOLICY_REPLACE/IGNORE, on which we trigger an error to catch any lingering uses and force updating of the BoardConfig.mk files, we only warn on uses of BOARD_SEPOLICY_UNION to avoid breaking the build until all device BoardConfig*.mk files have been updated, and since they should be harmless - the files will be unioned regardless.
