    [skip ci] Reduce zend.max_allowed_stack_size in gh20840.phpt

    This test still fails on i386 Windows with "Allowed memory size of %d bytes
    exhausted" because the output buffer grows too big. My first intuition was to
    add a chunk_size to ob_start, but this won't work if the output buffer is
    flushed deep into the call stack, causing a premature or just a second stack
    limit error. So, reduce the stack size in an attempt to produce less output.
