kernel-module-split: Append KERNEL_VERSION string to kernel module name 

The KERNEL_VERSION string is added to kernel module package names in order
to make the kernel modules for different kernel versions distinct packages
instead of different versions of the same package. With this change, when
a new kernel is installed together with its kernel modules (e.g. by upgrade
of the packages kernel and kernel-modules) using some package manager such
as apt-get or rpm, the kernel modules for the older kernel will not be
removed. This enables a fall back to the older kernel if the new one fails.

Also, for backwards compatibility and to enable kernel version agnostic
dependencies to kernel modules, create a virtual package with the old
(shorter) kernel module package name using RPROVIDES.
