Fix UnsatisfiedLinkError in CtsJvmti tests
A few CtsJvmti tests were failing due to the test setup racing with
the process that attaches the agent and loads the native library.
This change registers the native methods to fix the issue.
Bug: 112338190
Test: atest CtsJvmtiRedefineClassesHostTestCases \
CtsJvmtiTaggingHostTestCases \
CtsJvmtiTrackingHostTestCases
