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.

TEST=crostini tests pass

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'

It only supports playback streams, with capture streams to be added in
a different change.
