ANDROID: Incremental fs: Protect get_fill_block, and add a field
Since INCFS_IOC_GET_FILLED_BLOCKS potentially leaks information about usage
patterns, and is only useful to someone filling the file, best protect it in
the same way as INCFS_IOC_FILL_BLOCKS.
Add useful field data_block_out as well
Test: incfs_test passes
