kbuild: remove unnecessary $(subst $(obj)/, , ...) in modname-multi

In the context ...

    $(obj)/%.s: $(src)/%.c FORCE
            $(call if_changed_dep,cc_s_c)

    $(obj)/%.i: $(src)/%.c FORCE
            $(call if_changed_dep,cpp_i_c)

    $(obj)/%.o: $(src)/%.c $(recordmcount_source) $(objtool_dep) FORCE

            $(call if_changed_rule,cc_o_c)

    $(obj)/%.lst: $(src)/%.c FORCE
            $(call if_changed_dep,cc_lst_c)

'$*' returns the stem of the target (the part of '%'), so $(obj)/ has
already been ripped off.

$(subst $(obj)/,,$*.o) is the same as $*.o
