Fix makefile issues with cts_audio_quality

* Don't assume the install location of BUILD_HOST_NATIVE_TEST, it's
  changing from $(HOST_OUT)/bin to $(HOST_OUT)/nativetest...
* Remove temporary directories before use, to prevent incremental
  issues.
* Don't use host libstdc++, use our static version of libc++. It was
  actually linking to both, but falling back to the system's libc++,
  which may not be compatible with our version.
* Don't include headers from /usr/include. Our builds should only be
  using headers from the source tree.
