Fix compilation inside a container which may have some 3rd-party libraries loaded somewhere but not accessible with includeantruntime="false".

Otherwise get numerous errors trying to compile e.g. JavaMail- or JSCH-related tasks from inside NetBeans.
Would be cleaner for <available> to have an option to check in the specified classpath + bootstrap & extension loader, but not elsewhere;
lacking that, have to specifically not use ignoresystemclasses="true" on anything which is likely to be part of the JRE.
