  tree: relax the filemode parser
  
  There are many different broken filemodes in the wild so we need to
  protect against them and give something useful up the chain. Don't
  fail when reading a tree from the ODB but normalize the mode as best
  we can.
  
  As 664 is no longer a mode that we consider to be valid and gets
  normalized to 644, we can stop accepting it in the treebuilder. The
  library won't expose it to the user, so any invalid modes are a bug.
