sim: cr16: add ifdefs around undefined syscalls 

The cr16 libgloss port does not define these syscall numbers, so trying
to use them results in build failures [1].  The cr16 code already uses
ifdefs around a bunch of syscalls, so extend that style to cover the
ones that are currently missing.  Now we can at least compile.
