Use a smaller stack for stack-overflow test.

It is needed on FreeBSD to have a stack size < 125K to generate a SIGSEGV with
SEGV_ACCERR when using threads, and to have this test succeed.
Without that, the SIGSEGV is correctly generated, but with SEGV_MAPERR, and the
error message is not displayed.

I don't fully understand what's going on.

-> Try to increase stack size with --cfg=contexts/stack_size (current size is 8192 KiB).
