graph-depends: add option to pass arbitrary dot options

Kids nowaday seem to prefer a left-to-right drawing rather than the
more conventional and historical top-down drawing.

Rather than multiply the number of environment variables, just add
a single one where the user can pass arbitrary dot options, such as:

    make BR2_GRAPH_DOT_OPTS=-Grankdir=LR graph-depends
