Remove dead unused-parameter casts from copy_metadata()

Browse Source 
@gregmarr asked whether the static_cast<void> pair in the
JSON_DIAGNOSTIC_POSITIONS-off branch was needed for an empty
json_base_class_t. It isn't: src and dst are already referenced
unconditionally by the base-class copy above, so no -Wunused-parameter
warning fires either way (checked with -Wall -Wextra
-Wunused-parameter, JSON_DIAGNOSTIC_POSITIONS 0 and 1).
