tools build: Add feature test for libelf with ZSTD



The macro ELFCOMPRESS_ZSTD defines the compress algorithm, which was
introduced in the commit ("libelf: Document and make ELFCOMPRESS_ZSTD
usable with old system elf.h") of the repository elfutils-0.188-67.
Therefore, libelf 0.189 and later versions require to link the libzstd
library.

Add a test for checking if libelf supports ZSTD algorithm.  Pass the
macro ELFCOMPRESS_ZSTD as an argument to the elf_compress() function.
If the build succeeds, it means the feature is supported.
