Fix Ubuntu packaging of DVDNR (#425)

* Package DVDNR library properly for Ubuntu
- Incorrect name for DVDNR library was so used so library was not included in the package
- This did not block applications from running, since the library is loaded during runtime if found
- Without it Dolby Voice noise suppression and other processing was unavailable

* Bump version to 1.2.4
