Move to using full java-lib-files from stubs.

java-lib-header-files (turbine) differ from java-lib-files (actual metalava
output) in how the private constructors are showing up in these jars.

in classes.jar android/telephony/AccessNetworkConstants.class
package android.telephony;

public final class AccessNetworkConstants {
    private AccessNetworkConstants() {
        throw new RuntimeException("Stub!");
    }
}

in classes-header.jar android/telephony/AccessNetworkConstants.class
package android.telephony;

public final class AccessNetworkConstants {
}

As you can see, turbine seems to skip adding the private constructor,
which means that it becomes public.

Bug: 145933077
Test: m out/target/common/obj/api.xml
      out/target/common/obj/api.xml -> no longer has public constructor
      for AccessNetworkConstants
