In preparation for removing junit and android.test classes from
the Android API this change adds explicit dependencies on junit
and/or legacy-android-test to ensure that modules will compile
properly once it is removed.
Care was taken to ensure that any targets that depended,
directly or indirectly, on android-support-test did not also
depend on junit or hamcrest as they conflict with the versions
embedded within android-support-test.

Test: make checkbuild

Add LOCAL_DEX_PREOPT := false to force the samples to build actual apks.
In addition, fix a couple of other small issues:
- TtsEngine didn't have the api level set properly.
- SimpleJNI used a non-ndk library and was using libc++.
