This adds a default image recipe for building a RAUC update Bundle out of the
systems rootfs.
In order to sign your update (mandatory) you need to place a valid certificate
and key file in your BSP. Their location is
default they are currently expected to be located at:
$(PTXDIST_PLATFORMCONFIGDIR)/config/rauc/rauc.key.pem (key)
$(PTXDIST_PLATFORMCONFIGDIR)/config/rauc/rauc.cert.pem (cert)
PTXdist will then create the bundle during a run of `ptxdist images`.
