seccomp: remove redundant unconditional rules 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. I don't know what to do about the intentionally contradictory rules for open and openat, other than to remove then from the common device policy and add it to all the others. BUG=None TEST=Ran compile_seccomp_policy.py until it stopped complaining.
