runtime: remove obsolete osArchInit function

Browse source 
The osArchInit function was introduced as a workaround for a Linux kernel bug
that corrupted vector registers on x86 CPUs during signal delivery.
The bug was introduced in Linux 5.2 and fixed in 5.3.15, 5.4.2, and all 5.5 and later kernels.
The fix was also back-ported by major distros.
