[cache] Allow value 0 for face ID.
We never dereference `face_id', and some implementations might use a running number instead of a pointer. Additionally, disallowing value zero was undocumented. * src/cache/ftccmap.c (FTC_CMapCache_Lookup), src/cache/ftcmanag.c (FTC_Manager_LookupFace, FTC_Manager_RemoveFaceID): Remove test for `face_id'.
