[PATCH] Makefile: Fix of_list_dirs with EXT_DTB

[Manorit Chawdhry]

EXT_DTB overrides the of_list_dirs that is passed to binman during
builds. This causes binman to not find the normal DTB paths and instead
it just is able to use the path for EXT_DTB only.

Add the default of_list_dirs that is used for normal binman builds to
EXT_DTB usecase as well.
