[cache] Remove some casts, clean up tracing.

* src/cache/ftcbasic.c (FTC_ImageCache_Lookup, FTC_SBitCache_Lookup):
Clean up tracing types.
* src/cache/ftccache.c (ftc_node_destroy): Ditto.
* src/cache/ftcmanag.c (FTC_Manager_Check): Ditto.
(FTC_Manager_Check, FTC_Node_Unref): Remove a cast.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.
