Revert "Kernel: Make sure threads which don't do any syscalls are t..."

Browse source 
This reverts commit 3c3a1726df.

We cannot blindly kill threads just because they're not executing in a
system call. Being blocked (including in a page fault) needs proper
unblocking and potentially kernel stack cleanup before we can mark a
thread as Dying.

Fixes #8691
