list: fix segmentation fault with virtual packages
Virtual packages have the origin pointer set to NULL. Trying to print it using the BLOB_PRINTF macros causes a segmentation fault. Inspired by the `print_origin_name` function from `src/search.c` this commit attempts to fix it by checking whether `pkg->origin` is NULL before attempting to print it. If it is NULL the pkg name is printed instead. Since printing the pkg name requires a different format string this commit splits the printf call for printing the package line into multiple ones. The output format shouldn't have changed at all though.
