Tests: Add a test file for lzma_index_append() integer overflow bug.
This test fails before commit 18d7facd3802b55c287581405c4d49c98708c136.
test_files.sh now runs xz -l for bad-3-index-uncomp-overflow.xz
because only then the previously-buggy code path gets tested.
Normal decompression doesn't use lzma_index_append() at all.
Instead, lzma_index_hash functions are used and those already
did the overflow check.
