largefiles: fix 'hg clone . ../foo' OSError abort

Operating on a non-existant file can cause both IOError and OSError,
depending on the function used: open raises IOError, os.lstat raises
OSError.

The largefiles code called dirstate.normal, which in turn calls
os.lstat, so OSError is the right exception to catch here.
