David Tolnay 25a86d99cc tpm: Update tpm device policy to support libtpm2 
Tested by running the following on a grunt board (Barla) in dev mode
together with CL:1496910:

    sudo crosvm run \
        --root rootfs.ext4 \
        --socket crosvm.sock \
        --seccomp-policy-dir seccomp \
        --software-tpm \
        -p init=/bin/bash \
        -p panic=-1 \
        vmlinux.bin

and confirming that /dev/tpm0 and /dev/tpmrm0 are present in the VM.

I needed to override the common device policy's `open` and `openat` and
was not able to get that working with the existing @include.

Note: untested on arm.
