Handle task spawn attributes as task spawn file actions are handled. Why? This removes the need for sched_lock() when the task is being spawned. When loading the new task from a file the scheduler can be locked for a VERY LONG time, in the order of hundreds of milliseconds! This is unacceptable for real time operation. Also fixes a latent bug in exec_module, spawn_file_actions is executed at a bad location; when CONFIG_ARCH_ADDRENV=y actions will point to the new process's address environment (as it is temporarily instantiated at that point). Fix this by moving it to after addrenv_restore.
