[patch] Add preliminary readelf support for ELFCOMPRESS_ZSTD.

[ccoutant@gmail.com]

This patch adds support to readelf to recognize the new ELF compression
type. There is more work to be done to actually support compression and
decompression using the zstd library, but I will leave that to the
champions of the new compression option.
