This patch was originally made by Anel Husakovic.

Skip `PACKAGE` and `PACKAGE BODY` records quickly.

These stored objects do not have any parameters or return values
(only procedures and functions have).
So no needs to build a `CREATE` statement
(in `Sp_handler::sp_load_for_information_schema()`) and parse it:
this won't give us any data useful for `INFORMATION_SCHEMA.PARAMETERS`.
