Yafang Shao d4ee4ac395 security: replace memcpy() with get_task_comm() 
Quoted from Linus [0]:

  selinux never wanted a lock, and never wanted any kind of *consistent*
  result, it just wanted a *stable* result.

Using get_task_comm() to read the task comm ensures that the name is
always NUL-terminated, regardless of the source string. This approach also
facilitates future extensions to the task comm.
