(zipfs) Creating or updating a JAR file system should put the MANIFEST.MF at the start

JarInputStream requires META-INF/MANIFEST.MF to be the first or second entry in the JAR file. If a JAR file is created or updated with the JAR file system provider and META-INF/MANIFEST.MF exists then it should put this entry at the start of the JAR file to allow JarInputStream read it.
