From: Xiangyu Chen <xiangyu.chen@...>

Since we removed the openssh dependency[1] on rng-tools, there are no package requiring
rng-tools in oe-core, meta-oe, meta-virt, and the /dev/random won't block anymore after
linux-5.6[2], one of the reasons for keeping rng-tools build into the image is that it
can be used to test[3], so splitting the rng-tools systemd/systvinit service as a package.
If someone needs rng-tools daemon service, they can enable the rng-tools-service package by
directly.

V2 -> V3 changes:
fix missing INITSCRIPT_PACKAGE cause build failed under sysvinit environment

V1 -> V2 changes:
according to the review comments, using FILES/PACKAGES to split the service package instead of adding
a custom variable to disable the rngd daemon.
