-Exit with a special value when RNG modules are not available
-
-Instead of returning with an error, exit with a special value when the
-RNG kernel modules are not present in the kernel. This is not really a
-hard failure.

-Patch borrowed from Fedora, at
-http://pkgs.fedoraproject.org/cgit/rng-tools.git/tree/rngd-exit-code.patch.
