name-hash: add index_dir_find()
index_dir_exists() returns a boolean to indicate if there is a case-insensitive match in the directory name-hash, but does not provide the caller with the exact spelling of that match. Create index_dir_find() to do the case-insensitive search *and* optionally return the spelling of the matched directory prefix in a provided strbuf. To avoid code duplication, convert index_dir_exists() to be a trivial wrapper around the new index_dir_find().
