Subject: [PATCH 08/18] sysctl extern cleanup - latencytop

Extern declarations in sysctl.c should be move to their own head file,
and then include them in relavant .c files.

latencytop_enabled is declcared in linux/latencytop.h, so remove the
declaration in sysctl.c, include the head file instead.
