Enabling the security manager using a property, versus setting the property to `allow` and enabling it in code, is mostly a distinction without a difference. I don't think there is really a need to have the different tools be consistent. Local tool considerations probably swamp the need for any cross-tool consistency.

In this case some of the RMI registry tests set the property to `allow` on the command line and then rely on the code to enable the security manager using the API, so it's much easier to switch the `rmiregistry` launcher to use the `allow` technique instead. This is sort-of the tail (the tests) wagging the doc (the tool) but there doesn't seem to any benefit to be gained from fiddling around with the tests and the RMI test library.

I've also updated VersionCheck.java to filter out the security manager warning messages.
