MDEV-22653: Remove the useless parameter innodb_simulate_comp_failures

The debug parameter innodb_simulate_comp_failures injected compression
failures for ROW_FORMAT=COMPRESSED tables, breaking the pre-existing
logic that I had implemented in the InnoDB Plugin for MySQL 5.1 to prevent
compressed page overflows. A much better check is already achieved by
defining UNIV_ZIP_COPY at the compilation time.
(Only UNIV_ZIP_DEBUG is part of cmake -DWITH_INNODB_EXTRA_DEBUG=ON.)
