Fix buildCts.py Source Path

The buildCts.py script runs a JavaDoc command over the Android
java packages with a custom doclet that generates XML files that
CTS uses to create its test plans. Unfortunately, JavaDoc decides
to ignore a class if one of the classes in its inheritance hierarchy
is not found. Since the source path for frameworks/base/test-runner
was incorrect, all ActivityInstrumentationTestCases were being
excluded from the build. Fixing the source path should add roughly
1500 tests back into the CTS.
