[PATCH 0/6] cloud-hypervisor v52 and VM runtime fixes

[colbyt <colby@colbyt.com>]

This series fixes the VM runtime issues from the bug list and updates
Spectrum's patched Cloud Hypervisor package to 52.0.

The first patch vendors two skaware backports that were already being
applied.  The old cgit patch URLs can return the wrong patch, so keeping
the small diffs in-tree makes those builds reproducible again.

The Cloud Hypervisor patch rebases Spectrum's vhost-user GPU support
onto 52.0 and updates the paired rust-vmm/vhost checkout to
vhost-user-backend-v0.22.0.  The old local vhost shared-memory patches
are dropped because v0.22.0 already has the support needed by the GPU
frontend.

The rest of the series fixes the crosvm and installer issues: crosvm
test VMs use the existing passt-backed vhost-user-net path, the GPU
documentation uses crosvm's current --socket-path option, the installer
stops forwarding boot status noise to the console during graphical
startup, and start-vmm gains a regression test for the generated GPU
socket wiring.
