Previously, we rely on mount points to copy files out of efs partitions. Switch over to dump.f2fs to read directly from block device without mounting. This allows us to copy files out of efs partition in both 4K and 16K mode. Test: Boot dev option enabled ext4 device Bug: 340965747 Change-Id: I9d3f3d5200adc31f13298488b5be068b0fe7c7f4
