When a dyndbg classname is unknown to a kernel module (as before
previous patch), the callsite is un-addressable via >control queries.

The control-file displays this condition as "class unknown,"
currently.  That spelling is sub-optimal/too-generic, so change it to
"class:_UNKNOWN_" to loudly announce the erroneous situation, and to
make it uniquely greppable.
