PR to release hotfix v21.06.01 of cudf

Fixes #8514

String dictionary length is RLE encoded and rle_data_size and non_rle_data_size take this into account. However, When computing chunk stream offsets, these streams were treated as non-RLE and non_rle_data_size was not added. This caused discrepancy between non-RLE stream sizes and available space, leading to overlap between chunk streams.

Applied the non_rle_data_size to the offset to correct the discrepancy and added a test that uses decimal columns to increase the size of non-RLE encoded data and enable the overflow.
