First, ensure 'check-attr' reads the attributes in the untracked
.gitattributes...

Then, once .gitattributes is in the index, 'check-attr --cached' reads the
attributes from the index. Makes sense.

This test starts the same way as the last, ensuring a .gitattributes file on
disk is read. The difference is, this one is outside the sparse cone;
without the previous patch [1], this would not work correctly. Good!

Now, add the file to the index and reapply the sparse-checkout patterns. In
both 'sparse-checkout' and 'sparse-index', the file is removed from disk; in
'sparse-index', the file is now contained in a sparse directory. Despite
this, the attributes are still read correctly by 'check-attr --cached'. 

These tests look great to me!
