MDEV-27634 innodb_zip tests failing on s390x
Some GNU/Linux distributions ship a zlib that is modified to use the s390x DFLTCC instruction. That modification would essentially redefine compressBound(sourceLen) as (sourceLen * 16 + 2308) / 8 + 6. Let us relax the tests for InnoDB ROW_FORMAT=COMPRESSED to cope with such a weaker compression guarantee. create_table_info_t::row_size_is_acceptable(): Remove a bogus debug-only assertion that would fail to hold for the test innodb_zip.bug36169. The function page_zip_empty_size() may indeed return 0.
