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.

This is used in Rust 1.40.0's libstd in place of stat/fstat; update the
whitelists to allow the new syscall as well.

Add support for FS_IOC_{GET,SET}_ENCRYPTION_POLICY. Unfortunately,
since the I/O direction is encoded backwards in the ioctl definitions,
these will only work with on a kernel that's compiled with a patch to
mark them as unrestricted FUSE ioctls.
