dispatch.sh: Make dispatching actually work for rrsync and diff

Make it work. Basic BSD shell doesn't seem to have array support (read
failed and ${!VAR[@]} as well). Also I don't know integer arithmetic so
I do a runtime length for the loop.

As we don't put $MACHINE/$RELASE into an `` block we should be okay
and not run into remote execution.
