sparse: clean up config signature code

Before, 0 was being used as the default signature value and we cast
the int to a string. We also handled I/O exceptions manually.

The new code uses cfs.tryread() so we always feed data into the
hasher. The empty string does hash and and should be suitable
for input into a cache key.

The changes made the code simple enough that the separate checksum
function could be inlined.

#require bzr

  > wt = workingtree.WorkingTree.open('.')

  > message, ghostrev = sys.argv[1:]
  > wt.set_parent_ids(wt.get_parent_ids() + [ghostrev])
  > wt.commit(message)
  > EOF
