The framework_partition_set would be generated from
framework_item_list and we should respect this partition
set while merging META/ab_partitions.txt.
This is to handle the case when we use a complete merged
target files package as the framework-target-files, where
its ab_partitions.txt may have non-framework partitions.
So we need to filter them out to prevent from the merged
meta file has some partitions that don't exist.
Test: merge_target_files &&
add_img_to_target_files &&
img_from_target_files &&
flash device
