[Libguestfs] [PATCH] inspect: avoid returning "unknownX.Y" for unknown Linux distros

[Pino Toscano]

If it is not possible to detect the distribution of a Linux OS, do not
propose "unknownX.Y" (where X is the major version number, and Y the
minor) as short osinfo ID. Just return "unknown" instead.
