[Buildroot] [git commit branch/2019.11.x] package/lz4: security bump to version 1.9.2

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=8085c54159720b858e1a601fa946cae4a51486b7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.11.x

- Fix CVE-2019-17543: LZ4 before 1.9.2 has a heap-based buffer overflow
  in LZ4_write32 (related to LZ4_compress_destSize), affecting
  applications that call LZ4_compress_fast with a large input. (This
  issue can also lead to data corruption.) NOTE: the vendor states "only
  a few specific / uncommon usages of the API are at risk."
- Update indentation of hash file (two spaces)
