vms: Analyzed cipher/rndvms.c origins, updated copyrights

src/platform/vms/entropy.c is based on gnupg-1_4_9a_vms/cipher/rndvms.c, written
2006, 2007 by Steven M. Schweda. Licensed under the GNU GPL v3. Distributed with
the VMS port of GnuGP.

I see no single codeline in this file which could be traced back to the mentioned
cryptlib sources, copyrighted by 1996, 1997, 1998, 1999, Peter Gutmann
(and various others).
[codingstd] remove wrong copyright section, fix codingstd's

The previous copyright chapter had nothing to do with this source,
which is the solely work of antinode Steven M. Schweda for gnupg,
based on ideas from cryptlib.

Fix spaces and parens, documentation
[codingstd] more work on vms/exec.c

Documentation, indentation, reformating
