[C++] Replace erroneous return in EvalInclude()

We need to continue the loop, not abort the function, otherwise kati
will ignore include files that should not be ignored.

Test case:

 $ cat Makefile.minus-include-main
 .PHONY: default
 default:

 -include Makefile.minus-include-?
 $ cat Makefile.minus-include-a
 $(info include a...)
 $ cat Makefile.minus-include-b
 $(info include b...)

 $ ckati --warn --gen_all_targets --regen --ninja -f Makefile.minus-include-main
 include b...
 include a...
 $ ckati --warn --gen_all_targets --regen --ninja -f Makefile.minus-include-main --ignore_optional_include=Makefile.minus-include-a
 arguments changed, regenerating...
 include b...
 $ ckati --warn --gen_all_targets --regen --ninja -f Makefile.minus-include-main --ignore_optional_include=Makefile.minus-include-b
 arguments changed, regenerating...
