Generated override is not followed in gitattributes

[Nixinova]

Having gitattributes content such as

package-lock.json -linguist-generated

does not actually lead to the file being included in the output.

[Nixinova]

This occurs because default gitignored content is ignored when the list of files is being made so there is nothing to un-filter out when parsing gitattributes.

const data = walk({ init: true, commonRoot, folderRoots: resolvedInput, folders: resolvedInput, gitignores, regexIgnores });
files = data.files;
folders = data.folders;

Being worked on at the moment; requires quite a bit of a rewrite. Tests do not pass at this stage.

To be fixed in 2.7
