We are going to use separate policy files per device for the following scenarios:
1) Regular in-VMM virtio device,
2) Virtio device over vhost-user,
3) Virtio device over Vvu.
Each of these scenarios require slightly different policies as a jailed
device process needs to allow not only the system calls necessary for
the device to function, but also those required by the virtio transport
in use.
This CL adds a README.md file to the seccomp directory that details the
naming and policy inclusion rules, and updates the serial, xhci and
coiommu policies to follow the naming scheme.
Vhost-user and VVU policy files will be added along with support for
jailing devices when they are in use.
