attr.c: read .gitattributes from index as well.
This makes .gitattributes files to be read from the index when they are not checked out to the work tree. This is in line with the way we always allowed low-level tools to operate in sparsely checked out work tree in a reasonable way. It swaps the order of new file creation and converting the blob to work tree representation; otherwise when we are in the middle of checking out .gitattributes we would notice an empty but unwritten .gitattributes file in the work tree and will ignore the copy in the index.
