linux-info.eclass: linux-info_get_any_version, die on failure

Make linux-info_get_any_version die if it can't determine any version
of the Linux kernel. This indicates a problem with the eclass code
(as it should not happen on Linux) and the missing KV_* variables
are going to cause random misbehavior and failures.
