Use sysctl("machdep.cpu0.cpu_id") to retrieve the ARM64 cpu_id
information on netbsd/arm64. This includes the ISAR0, ISAR1 and PFR0
registers which can be parsed using existing functionality.
In order to use sysctl(3) without depending on x/sys/unix, some
functionality needed to be copied and slightly adjusted.
