buildserver: use android update sdk to install Android SDK

`android update sdk --no-ui` is the standard command line tool for
installing the Android SDK.  By symlinking into the $ANDROID_HOME/temp dir,
the cached files can still be used.  This converts the chef recipe to a
vagrant shell provisioning script since it was all bash anyway.

Some file names no longer officially have a -linux in them, so those were
changed to keep the cache working with the default filename.
