Pass public API list to class2greylist tool.
This is necessary to allow it to exclude synthetic bridge methods from the
generated greylist. We need to be able to apply the @UnsupportedAppUsage
annotation to regular (non-bridged) methods, but due to the SDK visibility
rules, the synthetic bridge is part of the SDK.
Don't do this on build that don't include frameworks/base since the
target is not needed and breaks certain builds.
