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.

This gives more CPU time to the daemons and requests are are more
important to run in a timely matter. We can see that we reach ipmid
coming up and multi-user ~20s faster on an ast2500.

The upstream rng-tools ships a systemd unit as a standard part of the
package now so we don't need to define our own custom one.

Adopt a more conventional directory hierarchy. meta-phosphor is still
a _long_ way from suitable for hosting on yoctoproject.org but things
like this don't help.
