description:
ddb(4): Declare extern db_active if _KMEMUSER too, not just DDB.

crash(8) is built with _KMEMUSER defined but DDB not defined except
for a few specific files or on MIPS.

Seems to me crash(8) should really be built with DDB defined in all
.c files but that leads to other fallout I'm not really inclined to
diagnose right now.
