Make all FrameBuilderTests run on RT

Test: adb shell /data/nativetest/hwui_unit_tests/hwui_unit_tests  --gtest_filter=FrameBuilder.renderNode_OpenGL
Test: adb shell /data/nativetest/hwui_unit_tests/hwui_unit_tests  --gtest_filter=FrameBuilder.projection*

They essentially all use Caches, so making RT-only for safety. This
prevents crashes when trying to access Caches in a non-rt test, when
it's not guaranteed to be created.
