Make `dua` less prone to hanging by ignoring certain special directories on linux.

### New Features

 - Add `--ignore-dirs` option, with useful default on linux.
   
   On linux there are a few directories which shouldn't be traversed by
   default as they may cause hangs and blocking.
   
   With the new argument it's possible to specify absolute directories
   to not enter during traversal, with a default set to avoid
   problematic directories on linux right away.
