libcab: add camera algorithm bridge

This initial version creates a service, arc-camera-algo, that adapts
the camera algorithm library. A camera HAL can utilize the camera
algorithm bridge to access the camera algorithm through IPC that is
built between the bridge and adapter.
The arc-camera-algo service, together with the camera algorithm, is
sandboxed using minijail0 with chroot and seccomp-bpf filter applied
such that minimum kernel surface is exposed and access to /dev/video* is
denied.
