Revert 188747 "Android WebView: change how the SDK jar is found."

> Android WebView: change how the SDK jar is found.
> 
> Setting android_sdk has unintended consequences which have recently
> broken the build, but we still need to be able to point to the sdk
> jarfile for now until this dependency has been solved for real; use the
> newly introduced android_sdk_jar variable from r188737 to specify this
> and set android_sdk to a harmless but invalid value rather than a make
> variable expansion.
