Log Message:
tests/kernel/t_time_arith.c: update for the recent kernel change

the test updates in the recent change was for some reasons incomplete.
("itimer_transition: do not keep it_value unchanged after firing the event")
https://mail-index.netbsd.org/source-changes/2026/03/17/msg161046.html

this commit updates the rest of tests.

tested with a full build and then the following command:
```
  # chroot destdir
  # cd /usr/tests/kernel
  # atf-run t_time_arith > /dev/null
  # echo $?
  0
  #
```

(the discussion is still ongoing, but this commit fixes
the test failure quickly. well, actually it was not that quick as
i had to calculate each expected values with bc.)
