sim: cr16: switch to new target-newlib-syscall

Use the new target-newlib-syscall module.  This is needed to merge all
the architectures into a single build, and cr16 has a custom syscall
table for its newlib/libgloss port.

This allows cleaning up the syscall ifdef logic.  We know these will
always exist now.
