fix build with ucommon 7.0

New version of ucommon adds some restriction to Digest class which
break the way twinkle is using it:

- proper initialization using constructor is needed
- c_str() method is gone; fortunately, str() result can be used to
  initialize std::string instead

Neither of these changes breaks build with ucommon 6.x.
