Few minor jpackage issues:

 - Remove debug logging of arguments at [1]. It looks like a leftover from some debug session years ago.
 - The default module path is not passed to jlink. A regression from JDK-8333664. jlink without an explicit "--module-path" option set to the default module path should work just fine, so this issue doesn't have a functional impact.
 - Fix incorrect configuration of BuildEnv instance in msi/exe bundlers. The directory for cooking app image when bundling msi/exe packages is supposed to be "${TMP}/image", but it is "${TMP}/image/${AppName}", which is correct for app image bundling, but not for msi/exe bundling. The issue doesn't have a functional impact.
