Subject: [PATCH v7d 02/23] dyndbg: reword "class unknown," to "class:_UNKNOWN_"

This appears in the control-file to report an unknown class-name, which
indicates that the class_id is not authorized, and dyndbg will ignore
changes to it.  Generally, this means that a DYNDBG_CLASSMAP_DEFINE or
DYNDBG_CLASSMAP_USE is missing.

But the word "unknown" appears in quite a few prdbg formats, so thats
a suboptimal search term to find occurrences of the problem.  Thus
change it to "_UNKNOWN_" which properly shouts the condition.
