The git submodule needs to be updated to work with newer chroot libssl.
In addition, the new OpenSSL version uses the getrandom syscall, so it
needs to be added to the seccomp policies.
TEST=build_test works again, vm's boot with a --software-tpm

The build-time seccomp compiler for aarch64 complains that it doesn't
recognize open, epoll_wait, recv, mmap2, dup2, poll, mkdir, or stat.
I tried to propose a change to upstream minijail to make it aware of
these syscalls, but the calls are in various forms of deprecation
so upstream is doubting the sanity of the policy files.
I applied the following mapping: open->openat, epoll_wait->epoll_pwait,
recv->recvfrom, mmap2->mmap, dup2->dup3, poll->ppoll, mkdir->mkdirat,
and stat->statx. In many cases the new syscall was already present so I
just deleted the old one.
BUG=None
TEST=Ran compile_seccomp_policy.py with an unmodified minijail until
it stopped complaining. I don't have an arm device for runtime testing.
Wrote an app to emulate the execution of the first 400 syscall #s though
the bpf filter and verified that the list that matches the filter is the
same as the policy file.

Minijail's policy compiler complains when there's multiple
unconditional rules for a syscall. In most cases the rules
are redundant to common_device.policy.
