[OE-core] [PATCH] update-rc.d: correctly look up the initscript params with overrides

[Ross Burton]

The creation of a clone of d with extra OVERRIDES was removed in
72c1fd72d3b479c728e249eaa763116d352e945b but some of the lookups are essential
so that variables such as ${INITSCRIPT_PARAMS} get overriden and resolved
correctly on a per-package basis.
