Improvements to standalone Android build scripts
* If multiple connected devices are detected, install.py prompts to
select one by default if no additional arguments are given.
* Add -a option to install.py that installs package to all connected
devices.
* Use ninja on Linux / OS X, if installed, for faster builds (apt-get
install ninja-build to get the awesomeness).
* If make is used, pass in -j{CPUs} based on number of cores detected.
* Prefer adb in path to avoid adb version mismatch in certain
environments, for example when doing Android OS builds.
* Clean up libs/ dir to avoid stale versions for archs that are not
being built.
* Do not unnecessarily force re-linking of libtestercore.so.
* Optimize asset cleanup by performing that only for the build that is
used for the assets.
* Auto-detect ANDROID_NDK_HOST_OS.
