grep: stop looking at random places for .gitattributes
grep searches for .gitattributes using "name" field in struct grep_source but that field is not real on-disk path name. For example, "grep pattern rev" fills the field with "rev:path", and Git looks for .gitattributes in the (non-existent but exploitable) path "rev:path" instead of "path". This patch passes real paths down to grep_source_load_driver() when: - grep on work tree - grep on the index - grep a commit (or a tag if it points to a commit) so that these cases look up .gitattributes at proper paths. .gitattributes lookup is disabled in all other cases.
