For #7852 37b3481

Small change to improve the format of the new MET covariance matrix (same as #7832, except for 75X instead of 74X). The new code is not configured to run, so it should not create any differences.

The code change is satisfactory, and the Jenkins tests against CMSSW_7_5_X_2015-02-19-1400 show no significant differences.
