Further reduce jacoco blacklist for libcore.

This takes advantage of the reduction in runtime dependencies of the
instrumentation code in http://ag/3505896. It reduces the number of
blacklisted classes in java.util from 10 to 3.

Bug: 64836607
Test: `cts-tradefed run cts-dev -m CtsLibcoreTestCases --test-arg com.android.compatibility.testtype.LibcoreTest:coverage:true` on a build with EMMA_INSTRUMENT=true and EMMA_INSTRUMENT_FRAMEWORK=true
