EROFS uses customized LZ4 decompression code for now (which has been offically
supported in lz4 1.8.3, I have updated it in
https://ozlabs.org/~akpm/mmots/broken-out/lib-lz4-update-lz4-decompressor-module.patch
if it is shown up in Linux 4.20, I will remove all the customized LZ4 decompression code),
but lib/ code lz4def.h isn't export to include/.

Thanks,
Gao Xiang
