* Add EINVAL errno testes for timerfd_create(2)
  - The clockid argument is neither CLOCK_MONOTONIC nor CLOCK_REALTIME,
    EINVAL would return.
  - flags is invalid, EINVAL would return.

* Add EBADF, EFAULT and EINVAL errno testes for timerfd_gettime(2)
  - fd is not a valid file descriptor, EBADF would return.
  - curr_value is not valid a pointer, EFAULT would return.
  - fd is not a valid timerfd file descriptor, EINVAL would return.

* Add EBADF, EFAULT and EINVAL errno testes for timerfd_settime(2)
  - fd is not a valid file descriptor, EBADF would return.
  - old_value is not valid a pointer, EFAULT would return.
  - fd is not a valid timerfd file descriptor, EINVAL would return.
  - flags is invalid, EINVAL would return.
