syntax: tweak the "no stack overflow" test
This test works by spinning up a thread with an atypically small stack size, parsing a regex into an Ast and then dropping it. We use a small stack size such that *if the Ast didn't have a custom Drop impl*, then its default recursive Drop impl would overflow the stack. (If we don't use a smaller stack size, then the default on some platforms is usually quite large and might require a much larger Ast to provoke a failure.) It turns out that the stack size we were using was quite tiny, and too tiny for some platforms such as FreeBSD. We therefore increase it a little bit, but not too much. We do the same for the corresponding test for the custom Drop impl for Hir. Fixes #967
