dev-java/rxtx: Fix USE=lfd issue (#550908), EAPI bump, cleanups

* lockdaemon.c should include limits.h
 * app-arch/zip can be implied using JAVA_PKG_IUSE
 * dev-java/ant-core isn't actually needed
 * sys-apps/xinetd is an RDEPEND, not DEPEND
 * Use the correct -source and -target flags
 * Remove useless elibtoolize
 * Remove useless sed
 * Add missing dies
 * dohtml is bad
