Revert "Update jacoco dependency to 0.7.5.201505241946"

JaCoCo 0.7.5 shows no lines covered when displayed by Jenkins JaCoCo
plugin 1.0.19.  Since Jenkins JaCoCo plugin 1.0.19 is based on JaCoCo
0.7.4 rather than 0.7.5, that may be expected.

The JaCoCo report in target/site/jacoco/index.html appears correct and
complete for JaCoCo 0.7.5, but the missing presentation in Jenkins means
this update needs to wait until the JaCoCo plugin is updated to support
JaCoCo 0.7.5.

Submitted JENKINS-28652 documenting the JaCoCo plugin problem

This reverts commit aa7e532a9fdd947abe131efc006c7119ed430a41.
