t1710: make hash independent

This test uses several index hashes, which necessarily depend on the
version of the index and the hash algorithm in use.  Use test_oid_cache
to provide values for these for both SHA-1 and SHA-256.  Also, compute
an object ID and use $EMPTY_BLOB to make the remainder of the tests
independent of the hash algorithm in use.
