We can add a field to struct tcb, but its semantics wrt memory management
should be strictly defined. For example, who is responsible for memory
deallocation, what droptcb() should do about this field, etc.
In this case, we probably need to store a pointer to a string dynamically
allocated in drm_get_driver_name() (on entering syscall) which is
automatically deallocated later in trace_syscall_exiting() and droptcb().
