urldetect: return osdict.py:OsMedia instead of Libosinfo.Media

Consequently, let's:
- rename urldetect::get_osinfo_media() to get_os_media()
- rename the installertreemedia::_LocationData::osinfo_media to os_media
- rename unattended::prepare_install_script's media argument to os_media
  - and also rename media to os_media on its internal
    _get_installation_source() method
- rename osdict::get_install_script's media argument to os_media
