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.

c8cff01c36 Specify prctl's policy only once per device
The libminijail version in AOSP complains when there are multiple entries for
the same system call, which was the case for virtio-fs's policy.

d4d0b5ccf3 crosvm: add more time syscalls to policies
glibc 2.32 is using clock_gettime/64 on some arm boards
when gettimeofday is used. In addition, support 64-bit
variants of the time syscalls for use with glibc 2.32.

f19933bfb0 tree-wide: seccomp: allow clock_nanosleep syscalls
Starting with 2.32 glibc nanosleep() was refactored to use the
clock_nanosleep syscall so various software will fail unless
the new syscall is allowed. We can't just drop the old nanosleep
syscall because it will break glibc 2.27 which is still used.

See glibc commits:
807edded25 nptl: Refactor thrd_sleep in terms of clock_nanosleep
3537ecb49c Refactor nanosleep in terms of clock_nanosleep
79a547b162 nptl: Move nanosleep implementation to libc

This is a bulk edit done with the following command:
git grep -rl 'nanosleep: 1' | xargs sed -i \
                           '/^nanosleep: 1/a clock_nanosleep: 1'
