package/rng-tools: add systemd support for rngd 

Add rngd.service for systemd. Also patch rngd with patch from Fedora to
ignore failure if no hwrng present:
https://bugzilla.redhat.com/show_bug.cgi?id=892178



[Thomas:
 - rename patch to the proper naming convention
 - add description and SoB to patch
 - install service file to /usr/lib/systemd and not /lib/systemd
 - use a relative symbolic link instead of an absolute one]

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.
