Augustin Cavalier 6554d7448d kernel: Print the first 4 chars of cvar names in KDL "threads" command.
Condition variables are now a pretty common way the kernel blocks threads.
That means the "threads" command was getting difficult to navigate, since
at any given time, a lot of threads could be blocked on "cvar".

Now we try (carefully, because it could fault!) to fetch the first 4
characters of the "type" name and display then. This suffices to
distinguish the most common object block types in the list at a glance
(e.g. "cvar:port" for port reads, the most common.)
