e1b483fc88 fuzz: Add fuzzer for virtio-rng 
To make the fuzzer faster and more effective, the guest memory is
setup with a much smaller size (comparing with other virtio device
fuzzers) and  a hole between the memory for holding virtio queue and
the rest of guest data. It brings two benefits: 1) avoid writing large
chunk of data from 'urandom' into the available descriptor chain (which
makes the fuzzer faster); 2) reduce substantial amount of overwrites to
the virtio queue data by the data from 'urandom (which makes the fuzzer
more deterministic and hence effective).

43c4270289 rpm: doc: Remove bundled SPEC and update README 
Packages targeting various distributions are now available thanks to the
Open Bulid Service. The SPECS have been moved to a separate repo under

https://github.com/cloud-hypervisor/obs-packaging

which documents how to include pre-compiled binaires in a supported
distribution. Besides the Cloud Hypervisor itself, accompanying pieces
like UEFI bins are available, too.

Any contributions to the packaging can be also accepted in
the aforementioned repo. Further integration with the OBS like PR
validation is to be targeted there, too, as far as it can get. As the
packaging topic has moved in a separate repo, the bundled SPEC became
obsolete is suggested for removal.

Fixes: #4257
