Fix lisp.h underparenthesization

* src/lisp.h (STACK_CONS, AUTO_STRING_WITH_LEN):
Parenthesize compound literals that are function call args.
Although this does not fix any bugs, it is the proper style for
macro parenthesization as it means this code will continue to
work even if make_lisp_ptr is changed to a macro.
