c11683b07f seccomp: add lseek to all devices
The panic hook calls read_to_string, which relies on lseek internally.
Most devices already allow lseek, but add it to the common policy files
to ensure that devices can properly panic.

BUG=None
TEST=compiles

1dab58a2cf Update all copyright headers to match new style
This search/replace updates all copyright notices to drop the
"All rights reserved", Use "ChromiumOS" instead of "Chromium OS"
and drops the trailing dots.

This fulfills the request from legal and unifies our notices.

./tools/health-check has been updated to only accept this style.

c553d1c283 seccomp: define naming rules for policy files
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.

BUG=b:217480043
TEST=serial device works with `crosvm run`.
