• change mksh to only then behave more POSuXish when called as /bin/sh or

“-sh” if -DMKSH_BINSHREDUCED was passed during compilation, for example
  for Debian, but d̲e̲f̲i̲n̲i̲t̲i̲v̲e̲l̲y̲ n̲̲o̲̲t̲̲ for MirBSD™
• split up regression test to force this behaviour
• remove the gunk from our MirBSD™ startup scripts again
• mention arc4random.c changes on website, sync clog, warn packagers
