cluster/ec: Change meaning of trusted.ec.dirty

- With this change, the xattr will represent if the file needs to be healed or
  not. It will have different values for data/entry and metadata changes.
- inode ref leaks and dict_set_dynstr related leaks fixed
- Added support for trylock/lock based on heal-cmd execution or not
  in data heal.
- Made fixes to pass regression runs
