Add knownfailures for jvmti-stress

Add a number of known-failures for the various jvmti-stress. Some of
these tests are flaky or failing and should be added so that --all
works better.

Test: ./test/testrunner/testrunner.py --optimizing      \
                                      --host            \
                                      --64              \
                                      --redefine-stress \
                                      --trace-stress    \
                                      --field-stress    \
                                      --step-stress
