rng-tools: use 'hw-rng' to disable libjitterentropy
The warrior version of rng-tools introduced an optional PACKAGECONFIG,
which was enabled by default, called `libjitterentropy`. For BMC chips
which have a hardware RNG, this is not a necessary feature, and causes
a noticeable delay in the start of the rngd. On systems with very low
IO activity we are seeing cases of what appears to be hangs.
Define a machine feature which can be used to disable the PACKAGECONFIG
for machines which contain a BMC chip with a hardware RNG. Aspeed has
one which is supported; Nuvoton currently does not.
