Fds created via dup don't share file descriptor flags with the original
fd, which means that they don't have the FD_CLOEXEC flag set. Use
fcntl(F_DUPFD_CLOEXEC) so that this flag gets set for the duplicated fds
as well.

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.

TEST=Ran compile_seccomp_policy.py until it stopped
complaining.

These policies are not for aarch64 but use the 32-bit system calls.
We call it aarch64 support because that's what we're targetting for
the guest kernel, but it doesn't really make any sense to call the
seccomp policies aarch64 when we're building a 32-bit binary.
We can add real aarch64 seccomp policies when we start building a
aarch64 crosvm binary.
