[AS7-6338] Remove -jaxpmodule from start scripts

Let David take a look first.

The calls to

    __JAXPRedirected.changeAll(loader.getModule().getIdentifier(), loader.getModule().getModuleLoader());

seem necessary, since that sets the default factories to use from the services imported by the boot loader. Without that, later the __XXXXFactory classes use the TCCL which might not initialize those services, and then fall back to the default set up by __JAXPRedirected.init() which gets called with the launcher classloader which does not have those services imported.
