Update flags for jdt-javac

Update the flags to match
https://github.com/eclipse-jdtls/eclipse-jdt-core-incubator/blob/dom-with-javac/org.eclipse.jdt.core.javac/META-INF/p2.inf

This opens a bunch of jdk internals that the jdt-javac work uses,
and also sets the flags to enable the javac-based search.
