Makefile: Documentation for external tool should be correct
If one includes documentation for an external tool, it should be
correct. This is not:
1. Overriding the input to rngd should typically be neither
necessary nor desired. This is especially so since newer
versions of rngd support a number of different *types* of sources.
2. The default kernel-exported device is called /dev/hwrng not
/dev/hwrandom nor /dev/hw_random (both of which were used in the
past; however, kernel and udev seem to have converged on
/dev/hwrng.)
Overall it is better if the documentation for rngd is kept with rngd
rather than in a kernel Makefile.
