alpha: copy_thread(): rename 'arg' argument to 'kthread_arg'

Browse source 
The 'arg' argument to copy_thread() is only ever used when forking a new
kernel thread. Hence, rename it to 'kthread_arg' for clarity (and consistency
with do_fork() and other arch-specific implementations of copy_thread()).
