chain.c: we can't rely on dosmem and int13 in here...

dosmem and int13 can change during boot loader shutdown.  It
is therefore unsafe to rely on them retaining their value from
running in chain.c32 itself.  Instead, we have to install a
suitable stub which makes that particular determination at
runtime.  Fortunately that is not all that hard to do.
