cbfstool: Clean up in preparation for adding new files

Browse Source 
This enables more warnings on the cbfstool codebase and fixes the
issues that surface as a result. A memory leak that used to occur
when compressing files with lzma is also found and fixed.
Finally, there are several fixes for the Makefile:
 - Its autodependencies used to be broken because the target for
   the .dependencies file was misnamed; this meant that Make
   didn't know how to rebuild the file, and so would silently
   skip the step of updating it before including it.
 - The ability to build to a custom output directory by defining
   the obj variable had bitrotted.
 - The default value of the obj variable was causing implicit
   rules not to apply when specifying a file as a target without
   providing a custom value for obj.
 - Add a distclean target for removing the .dependencies file.

BUG=chromium:461875
