Use the non-cgo version for all openbsd architectures.
The old code only pulled some defines from header files. Just add them
as enumerations in native go. Also be careful at what the SysctlRaw returns.
Implement a way that supports both recent and old pre-6.4 OpenBSD systems.
With go-1.16 OpenBSD binaries will link to libc and because of this binaries
built on OpenBSD 6.9-current do not run on OpenBSD 6.3. OpenBSD 6.3 is also
not supported for more then 2 years. So maybe the compat code is not needed.
Still validation object length before doing an unsafe pointer conversion
is probably reasonable but I'm no golang expert.

Starting with (not yet released) OpenBSD 6.4, sysctl KERN_CPTIME2 will
return ENODEV for offline CPUs.
SMT siblings are reported as offline when hw.smt is disabled, which is
the default since one of the later Spectre variants. So this might
affect a few systems.
