[Crash-utility] Adding the zram decompression algorithm "lzo-rle" to support kernel versions >= 5.1

In Linux 5.1, the ZRAM block driver has changed its default compressor from "lzo" to "lzo-rle" to enhance LZO compression support. However, crash does not support the improved LZO algorithm, resulting in failure when reading memory.       change default compressor : ce82f19fd5809f0cf87ea9f753c5cc65ca0673d6<https://github.com/torvalds/l... The issue was discovered when using the extension 'gcore' to generate a process coredump, which was found to be incomplete and unable to be opened properly with gdb. This patch is for Crash-utility tool, it enables the Crash-utility to support decompression of the "lzo-rle" compression algorithm used in zram. The patch has been tested with vmcore files from kernel version 5.4, and successfully allows reading of memory compressed with the zram compression algorithm. Thanks and regards, Yulong
