[PATCH 3/3] module: Move mod_unload_taint to tracking.c

[Petr Pavlu]

Move the definition of mod_unload_taint from internal.h to tracking.c, as
it doesn't need to be exposed to other module code, and remove the
redundant declaration of mod_debugfs_root from tracking.c, as it is already
declared in internal.h.

This is a non-functional change.
