Include jacoco in core-libart for full coverage build

When building with EMMA_INSTRUMENT=true, coverage classes must be
available everywhere (so all apps can run with code coverage without
including those classes).

This CL includes jacoco into core-libart so it's available in the
bootclasspath (only when EMMA_INSTRUMENT=true).
