Kernel: Allocate new main thread stack before committing to exec

Browse source 
If the allocation fails (e.g ENOMEM) we want to simply return an error
from sys$execve() and continue executing the current executable.

This patch also moves make_userspace_stack_for_main_thread() out of the
Thread class since it had nothing in particular to do with Thread.
