[Android] Fix issue of make_apk does not work with Andorid SDK tools 23.

Android SDK tools 23 moves the 'zipalign' to $SDK_ROOT/build-tools, this
does not compatible with older SDK versions wich put 'zipalign' under
$SDK_ROOT/tools

Update the patch to make make_apk compatible with Android SDK tools 23.
