largefiles: fix 'hg status' abort after merge

If a largefile is introduced on the branch that is merged into the
working copy, then 'hg status' would abort with an error like:

   $ hg status
   abort: .hglf/foo@33fdd332ec64: not found in manifest!

The problem was that the largefiles status code only looked in the
first parent for the largefile. Largefiles are now always reported as
modified if they don't exist in the first parent -- this matches the
behavior of localrepo.status for normal files.
