Make slight adjustment to check(11, "SumsOfSquares") problem

After "format" bug fix, an entry of an input matrix was slightly
different (-7.99999.. instead of -8), which led to CSDP getting stuck
at edge of primal feasibility and giving up on the GitHub Ubuntu 24.04
runners.  We change the numbers slightly to avoid this.
