helper/test-oid-array.c along with t0064-oid-array.sh test the oid-array.h API, which provides storage and processing efficiency over large lists of object identifiers. Migrate them to the unit testing framework for better runtime performance and efficiency. As we don't initialize a repository in these tests, the hash algo that functions like oid_array_lookup() use is not initialized, therefore call repo_set_hash_algo() to initialize it. And init_hash_algo():lib-oid.c can aid in this process, so make it public.
