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.
