runtime: use hw.ncpuonline sysctl in getncpu on openbsd
The number of CPUs reported by the hw.ncpu sysctl is twice as high as
the actual number of CPUs running on OpenBSD 6.4. with hyperthreading
disabled (hw.smt=0). Try hw.cpuonline first and fall back to hw.ncpu
in case it fails (which is the case on older OpenBSD before 6.4).
Fixes #30127
