chore(cli): Don't assume deno is in path for spawn_kill_permissions (#19198)

We don't need to use the `deno` command here to test kill permissions
and it's awkward to get right without passing `-A`. `cat` works, but for
platforms other than windows. This test should have plenty of coverage
on other platforms.
