runtime: remove remaining use of MAKECONTEXT_STACK_TOP macro 

The definition and most uses of MAKECONTEXT_STACK_TOP were removed in
    https://golang.org/cl/88660043, which removed support for Solaris 8/9.
    One use of MAKECONTEXT_STACK_TOP was accidentally left in the source
    code.  Remove it now.
