[chore](build) add apache-orc git submodule path (#18695)

1. Add apache-orc git submodule update path, not update all modules
When sh build.sh, update all modules will fails serveral times because of unstable github network.
It wastes many time.

2. Add gitignore for  be/src/apache-orc/   to avoid mistake commits.
