libelf: check decompressed ZSTD size
Decompression functions like __libelf_decompress_zlib check that
decompressed data has the same size as it was declared in the header
(size_out argument). The same check is now added to
__libelf_decompress_zstd to make sure that the whole allocated buffer is
initialized.
* libelf/elf_compress.c (__libelf_decompress_zstd): Use return value
of ZSTD_decompress to check that decompressed data size is the
same as size_out of the buffer that was allocated.
