core: drop now-useless prepare-kconfig rule

This rule was added back in 9429e7b698 (core: introduce an intermediate
rule before the configurators) when the kconfig-side br2-external file
was generated separately from the Makefile-side one.

Now that they are generated together very early in the Makefile, we no
longer need this intermediate rule. Drop it.
