Add expected file for 095-recursive-define test case.

It's clear enough that the current segmentation fault isn't what we
want. And it's also very easy to know what we do want here, (just
check with any functional C preprocessor such as "gcc -E").

Add the desired output as an expected file so that the test suite
gives useful output, (showing the omitted output and the segfault),
rather than just reporting "No such file" for the expected file.
