meta-phosphor: remove obmc-rng feature

Since Linux 5.6, the entropy generation provided by rng-tools is now
in the kernel directly.  Yocto has removed all dependencies on rng-tools
for packages that use to use it, such as ssh[1].  There isn't any reason
for us to explicitly include rng-tools any longer.  Remove the feature
and package group that we had that included it.
