attr: convert git_check_attrs() callers to use the new API

The remaining callers are all simple "I have N attributes I am
interested in.  I'll ask about them with various paths one by one".

After this step, no caller to git_check_attrs() remains.  After
removing it, we can extend "struct attr_check" struct with data
that can be used in optimizing the query for the specific N
attributes it contains.
